QEMM automatically provides 8K-24K more memory for running DOS programs inside Windows 386 enhanced mode. Also, you can use QEMM's VIDRAM feature to extend the amount of memory available to DOS text-based programs running in Windows by up to 96K. (For information, see Chapter 6 in the QEMM manual.) If you install Windows after installing QEMM, be sure to run QSETUP and select "Specify Microsoft Windows directory." This selection will add the line SystemROMBreakPoint=false to your SYSTEM.INI file, a Windows configuration file, to ensure that Windows runs optimally with QEMM. ■τQEMM and Microsoft Windows (Continued) In the unlikely event that you experience problems with Windows after installing QEMM, see the text file WINFLOW.TEC in the \QEMM\TECHNOTE directory. You can view technotes with QEMM Setup by selecting "View QEMM hints technotes and READ.ME" at main menu. ■τQEMM and DESQview or DESQview/X If you are using DESQview or DESQview/X, you can increase the amount of memory in each window by using the Stealth ROM feature. To find out if you are using Stealth ROM, select "Review or change QEMM parameters" from the main QEMM Setup menu. Then look for the selection "Stealth system and video ROMs." If you see the word "Mapping" or "Frame" at the end of that line, Stealth ROM is already enabled. If you see the word "Off," you can enable Stealth ROM by typing "S" or hitting the ENTER key, then following the on-screen instructions. Online Help will tell you more about the Mapping and Frame methods of Stealth ROM. If you have DOS version 5 or 6, QEMM's installation places the command DOS=HIGH in your CONFIG.SYS file (if it is not already ■τQEMM and DESQview or DESQview/X (Continued) there). This is a DOS command that loads part of DOS and DOS BUFFERS into the HMA (the first 64K of memory above 1MB). You may be able to increase the amount of memory in DESQview or DESQview/X windows by deleting DOS=HIGH from CONFIG.SYS. To find out, first run Memory Status from inside DESQview or DESQview/X. Make a note of the figure in the bottom right under "Largest Available Expanded Memory." Then delete DOS=HIGH from your CONFIG.SYS and run Optimize by typing OPTIMIZE at the DOS prompt. When Optimize completes, run Memory Status from inside DESQview or DESQview/X and check "Largest Available Expanded Memory" again. If it is a larger number than before, you are better off ■τQEMM and DESQview or DESQview/X (Continued) without DOS=HIGH. Otherwise, add the line DOS=HIGH back to CONFIG.SYS and re-run Optimize. ■τQEMM and DR DOS 6 DOS-Up is compatible with DR DOS 6, but not DR DOS 5. Like DOS-Up, DR DOS can load selected parts of DOS into upper memory. However, we recommend you use DOS-Up. When you use DOS- Up, Optimize can control where in upper memory the parts of DOS are loaded; this helps ensure that upper memory is used as efficiently as possible. You may have to make a few changes to your CONFIG.SYS file so that DOS-Up will work efficiently with DR DOS 6. For complete information on using QEMM with DR DOS 6, see the text file DRDOS6.TEC in the \QEMM\TECHNOTE directory. You can view technotes with QEMM Setup by selecting "View QEMM hints technotes and READ.ME" at the main menu. ■τQEMM and Disk Compressors ■τ(e.g., Stacker, SuperStor) Depending on the disk compressor you are using, you may need to take special steps to use QEMM. We have provided technical bulletins (technotes) covering Stacker, SuperStor, XtraDrive, and DoubleDisk in the \QEMM\TECHNOTE directory. ■ΦStacker ■µ - If you have Stacker version 2.0x, 3.0 or 3.1, no special steps are generally required; however, we do suggest you read the technote STACKER3.TEC before running Optimize. ■τUsing QEMM with Disk Compressors (Continued) ■ΦSuperStor ■µ - Before running Optimize, read SSTOR.TEC. ■ΦXtraDrive ■µ - Please see the technote XTRADRV.TEC. ■ΦDoubleDisk ■µ - Before running Optimize, see DBLDISK.TEC. ■ΦDoubleSpace ■µ - If you are using MS-DOS 6's DoubleSpace, you can save 40K of memory by using QEMM's Stealth DoubleSpace feature to relocate the DoubleSpace device driver in expanded memory. See Chapter 5 of the QEMM manual for details. ■τQEMM and Bus-Mastering Devices Certain SCSI disk controller cards (and, less frequently, ESDI disk controllers and network cards) use a technique called bus-mastering to speed up disk access. This technique causes a conflict when a memory manager (such as QEMM) attempts to load a device driver or TSR into upper memory. In some, but not all, cases QEMM can detect a bus-mastering hard disk controller and will take steps to prevent this from happening. (This is not true if the card controls something other than a hard drive or if QEMM is not being loaded from the bus-mastering hard drive.) The typical symptom of a bus-mastering controller is a lock up during Optimize. ■τQEMM and Bus-Mastering Devices (Continued) Fortunately, there are solutions to this problem. For a detailed explanation of bus-mastering and suggestions for resolving the conflicts caused by its use, please refer to our technical bulletin BUS-MAST.TEC which can be found in your \QEMM\TECHNOTE directory. You can view technotes with QEMM Setup by selecting "View QEMM hints technotes and READ.ME" at the main menu. ■τQEMM and the EMS Page Frame Most programs that use expanded memory (EMS) access up to 64K of expanded memory at a time (in 16K units called pages) at a special area of upper memory called the page frame. An expanded memory manager (QEMM) makes memory from outside the first megabyte of memory appear in the page frame. QEMM's installation normally reserves 64K of upper memory for use as a page frame. You can use QSETUP to specify that no page frame should be used. The advantage of eliminating the page frame is that you will free up 64K of upper memory. The disadvantages are 1) programs that use EMS memory will not have it, and 2) you will not be able to ■τQEMM and the EMS Page Frame (Continued) use the Stealth ROM and Stealth DoubleSpace features, which can typically gain you 48K-115K of additional usable upper memory, and 40K beyond that if you are using MS-DOS 6's DoubleSpace disk compression feature. Because a great number of DOS applications can use EMS memory and because you can gain even more usable upper memory with Stealth, we recommend you use a page frame. To eliminate the page frame, select "Review or change QEMM parameters" from the main QEMM Setup menu, then select "Set page frame" and specify NONE. To help you decide if you need a page frame, press PgDn see the partial list of programs that use EMS. ■τApplications that use EMS ■τProduct Publisher Paradox Borland Clipper Computer Associates DESQview Quarterdeck Folio Views Folio Corp.

Stealth ROM hides your PC's ROMs and makes their memory addresses available for High RAM or expanded memory mapping. The advantage of having the additional High RAM is that QEMM can load TSRs, device drivers and selected parts of DOS there instead of in conventional memory. By freeing up conventional memory, you will have more room for running DOS programs. Depending on your configuration and the installation options you chose, Stealth ROM may have been enabled on your system when you installed QEMM. When you run the Optimize program, Optimize ■τQEMM's Stealth ROM Feature (Continued) will try to load your TSRs, device drivers and selected parts of DOS into High RAM. If all of them will not fit, Optimize will test your system for compatibility with Stealth ROM and will determine which Stealth ROM method is best for your system. Is there any reason not to use Stealth? Yes, you may not need it if all your device drivers, TSRs and parts of DOS fit into High RAM without Stealth ROM enabled. The extra High RAM that Stealth ROM creates actually comes from QEMM's pool of memory, so by not using Stealth ROM you have slightly more memory for programs that use expanded or extended memory. A good rule of thumb is to let ■τQEMM's Stealth ROM Feature (Continued) Optimize decide whether you need Stealth ROM--if Optimize does not suggest Stealth testing, you do not need Stealth ROM. There is one exception--we recommend you use Stealth if you use DESQview or DESQview/X (see below). Also, there are a few machines that are incompatible with Stealth ROM; Optimize attempts to detect incompatibitiles during Stealth testing and will not enable Stealth ROM on machines that it finds are incompatible. DESQview and DESQview/X can use the additional High RAM provided by Stealth ROM. So if you regularly use DESQview or DESQview/X, we recommend you use Stealth ROM, even if Optimize did not ■τQEMM's Stealth ROM Feature (Continued) recommend it. To find out if you are using Stealth ROM, type QEMM at the DOS prompt. QEMM will display some status information. If you see information about the "Stealth type," Stealth ROM is already enabled. If not, you can have Optimize perform Stealth ROM testing by typing OPTIMIZE /ST. ■τQEMM's Optimize Program Optimize is a program that determines how to load TSRs, device drivers and selected parts of DOS into upper memory. Optimize analyzes the memory requirements of device drivers and TSRs that you are loading from CONFIG.SYS and AUTOEXEC.BAT and any batch files called by AUTOEXEC.BAT. Then, Optimize determines the most efficient way to load items into High RAM by testing all possible locations. There can be thousands or millions of possibilities. The object is to free up as much conventional memory as possible for your DOS programs. If you are using QEMM's DOS-Up feature, Optimize also experiments with different ways of loading parts of DOS into upper memory. ■τQEMM's Optimize Program (Continued) When you install QEMM, INSTALL offers to run Optimize. You should run Optimize again if you add new hardware devices or modify your AUTOEXEC.BAT or CONFIG.SYS files. Optimize must reboot your machine two or more times to complete its testing. Optimize changes the lines that load device drivers and TSRs by adding a LOADHI command to the beginning of those lines. For example, a device driver line that looks like this: ■ΦDEVICE=C:\DOS\SETVER.EXE would look something like this after Optimize has done its work: ■τQEMM's Optimize Program (Continued) ■ΦDEVICE=C:\QEMM\LOADHI.SYS /R:1 C:\DOS\SETVER.EXE A TSR line in AUTOEXEC.BAT that looks like this: ■ΦC:\DOS\SMARTDRV.EXE would look something like this after running Optimize: ■ΦC:\QEMM\LOADHI /R:2 C:\DOS\SMARTDRV.EXE For detailed information on Optimize, see Chapter 3 of the QEMM manual. For information on the LOADHI command, see Chapter 8. ■τUndoing an Optimize When you run QEMM's Optimize program, modifications are made to your CONFIG.SYS and AUTOEXEC.BAT files and any batch file called by AUTOEXEC.BAT. If for some reason you want to restore these files to their pre- optimized states, type UNOPT at the DOS prompt. The files will be restored to the state they were in before you last ran Optimize. ■τThe Manifest Program Manifest is a powerful system reporting program that is automatically installed on your hard drive when you install QEMM. While Manifest can be extremely useful when troubleshooting a problem, it is much more than a diagnostic tool. Whether you are new to computers or a power user with years of DOS experience under your belt, Manifest will help you take full advantage of the memory that is installed in your computer. Think of Manifest and its companion manual as a tutorial in memory management. To run Manifest, just type MFT at the DOS prompt. Open your Manifest manual to Chapter Three - Road Map, then take Manifest for a spin. At your own pace explore the world of memory as it relates to your own PC. ■τVIDRAM - Extending Memory for Text-based Programs QEMM's VIDRAM program can extend conventional memory by as much as 96K for running DOS text-based programs. VIDRAM even extends conventional memory for DOS text programs running in Microsoft Windows. To use VIDRAM, your system must have an EGA or VGA video adapter or an adapter with EGA or VGA capability (this includes VGA- compatible 8514A video adapters). Your PC must have 640K of conventional memory and the programs that you run while using VIDRAM must not use EGA or VGA graphics. ■τVIDRAM - Extending Memory for Text-based Programs (Continued) If your PC has an EGA or VGA video adapter, the 64K memory area just above conventional memory (640K-704K or A000-AFFF hex) is reserved for use by graphics modes. When you run text-based programs, that area is unused, so VIDRAM can appropriate it to extend the contiguous conventional memory for running programs. It is important to understand that you cannot run EGA or VGA graphics operations while VIDRAM is in use. If you routinely use both large text-based programs and graphics programs, you can turn the VIDRAM feature on when you need it for a text program and off before you run a graphics program. If you are using an 8514A adapter, you can still use 8514 graphics programs while VIDRAM is enabled. ■τVIDRAM - Extending Memory for Text-based Programs (Continued) To turn VIDRAM on type VIDRAM ON at the DOS prompt. This command will extend conventional memory into the EGA/VGA graphics area for a total of 704K conventional memory. To turn VIDRAM off so you can use graphics programs again, type VIDRAM OFF. For more information on VIDRAM, including using VIDRAM with Microsoft Windows, DESQview, and DESQview/X, and extending conventional memory an additional 32K, see Chapter 6 of the QEMM manual. ■τTips on Freeing Up More Conventional Memory If you use DOS text-based programs, you can extend conventional memory by as much as 96K by using QEMM's VIDRAM feature. For information on VIDRAM, see Chapter 6 of the QEMM manual. The Manifest program may be able to tell you how to free up a bit more conventional memory. Run Manifest by typing MFT at the DOS prompt. When Manifest displays, type H to select Hints, and read the suggestions Manifest offers. If you do not use any programs that require DPMI (DOS Protected Mode Interface) memory, you can free up 1-2K, by deleting the QDPMI.SYS device driver line from your CONFIG.SYS file. ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT QEMM's installation, Optimize and QSETUP programs modify your CONFIG.SYS and AUTOEXEC.BAT files and any batch file called by AUTOEXEC.BAT. In the examples below, the parameter /R:n loads an item into a specified High RAM region. On your system, the n is replaced by a number indicating the region. If you are using QEMM's DOS-Up feature, the following line is added at the beginning of CONFIG.SYS to prepare your system for loading parts of DOS into upper memory: ■ΦDEVICE=C:\QEMM\DOSDATA.SYS ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) Next, QEMM's installation adds the following line: ■ΦDEVICE=\QEMM\QEMM386.SYS R:n RAM This is QEMM's device driver line; it is the line that loads QEMM whenever you boot your PC. Depending on your configuration, you may see other parameters (e.g., ST:M or ST:F for Stealth ROM). If you are using DOS-Up, the following line appears after the QEMM386.SYS line: ■ΦDEVICE=C:\QEMM\DOS-UP.SYS @C:\QEMM\DOS-UP.DAT ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) The following statement (on one line) loads QEMM's DPMI driver: ■ΦDEVICE=C:\QEMM\LOADHI.SYS /R:n C:\QEMM\QDPMI.SYS ■ΦSWAPFILE=DPMI.SWP SWAPSIZE=1024 The following syntax is added to the beginning of other device driver lines in CONFIG.SYS: ■ΦDEVICE=C:\QEMM\LOADHI.SYS /R:n This command loads the device driver directly following this command into High RAM. (If a driver does not fit into High RAM, this syntax is not added.) ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) For example, if before installing QEMM, CONFIG.SYS contained the line DEVICE=C:\DOS\ANSI.SYS, Optimize would change it as follows: ■ΦDEVICE=C:\QEMM\LOADHI.SYS /R:n C:\DOS\ANSI.SYS If you want to manually remove the LOADHI command, you would delete C:\QEMM\LOADHI.SYS /R:n and the space directly following the number represented by n. The line would then look like this: ■ΦDEVICE=C:\DOS\ANSI.SYS. ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) If you are using DOS-Up, Optimize will add QEMM's LOADHI command to your SHELL line to load your command processor high (if you do not have a SHELL line, Optimize will add one for you). For example, if you have the following line in your CONFIG.SYS file ■ΦSHELL=C:\DOS\COMMAND.COM C:\DOS\ /P Optimize will change it to read as follows: ■ΦSHELL=C:\QEMM\LOADHI.COM /R:x C:\DOS\COMMAND.COM C:\DOS\ /P ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) If you are using DOS version 5 or 6, QEMM's installation will add the line DOS=HIGH to your CONFIG.SYS file if it is not already there. This is a DOS command that loads part of DOS into the HMA (the first 64K of extended memory). If you are using MS-DOS 6's DoubleSpace disk compressor, QEMM's installation will add the following line to enable the Stealth DoubleSpace feature: ■ΦDEVICE=C:\QEMM\LOADHI.SYS C:\QEMM\ST-DBL.SYS ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) QEMM's installation will remove device driver lines for other memory managers from CONFIG.SYS. Optimize makes the following changes to AUTOEXEC.BAT and to any batch file called by AUTOEXEC.BAT: QEMM's directory is added to your PATH statement. The following syntax is added to the beginning of lines that load TSRs (i.e., memory-resident programs) high: ■ΦC:\QEMM\LOADHI /R:n ■τQEMM and CONFIG.SYS and AUTOEXEC.BAT (Continued) This command tells QEMM to load the TSR directly following this command into High RAM. For example, if before installing QEMM, your AUTOEXEC.BAT file contained the line C:\NET\NETX.COM, Optimize would change it to read as follows: ■ΦC:\QEMM\LOADHI /R:n C:\NET\NETX.COM If you ever want to manually remove the LOADHI command, delete C:\QEMM\LOADHI /R:n. If you have MS Windows, QEMM adds SystemROMBreakPoint=FALSE to Windows' SYSTEM.INI file so Windows will run optimally with QEMM. ■τQEMM's New Parameter Names If you have upgraded from an earlier version of QEMM, be aware that many of the old parameters have new names. You can still use the older parameter names if you like. Below is a list of the old parameter names, cross-referenced with the parameters' new names. Some parameters have abbreviations which are listed in parentheses. ■τOld Name New Name COMPAQ386S (C386S) COMPAQ386S:Y (C386S) COMPAQEGAROM (CER) COMPAQEGAROM:Y (CER) COMPAQHALFROM (CHR) COMPAQHALFROM:Y (CHR) COMPAQROMMEMORY (CRM) COMPAQROMMEMORY:Y (CRM) ■τQEMM's New Parameter Names (Continued) ■τOld Name New Name DONTUSEXMS (DUX) USEXMS:N DOS4 (D4) DOS4:Y (D4) FORCEEMS (FEMS) FORCEEMS:Y (FEMS) FORCESTEALTHCOPY (FSTC) FORCESTEALTHCOPY:Y (FSTC) IGNOREA20 (IA) TRAP8042:Y (T8) LOCKDMA (LD) LOCKDMA:Y (LD) NOCOMPAQFEATURES (NCF) COMPAQFEATURES:N (CF) NOEMS EMS:N NOFILL (NO) FILL:N NOHMA HMA:N ■τQEMM's New Parameter Names (Continued) ■τOld Name New Name NOPAUSEONERROR (NOPE) PAUSEONERROR:Y (PE) NOROM (NR) MAPREBOOT:N (MR) NOROMHOLES (NRH) ROMHOLES:N (RH) NOSHADOWRAM (NOSH) SHADOWRAM:NONE (SH) NOTOKENRING (NTR) TOKENRING:N (TR) NOTOPMEMORY (NT) TOPMEMORY:N (TM) NOVDS VDS:N NOVIDEOFILL (NV) VIDEOFILL:N (VF) NOVIDEORAM (NVR) VIDEORAM:N (VR) ■τQEMM's New Parameter Names (Continued) ■τOld Name New Name NOWINDOWS3 (NW3) WINDOWS3:N (W3) NOXBDA (NX) XBDA:N NOXMS XMS:N OLDDV (ODV) OLDDV:Y (ODV) UNUSUALEXT (UX) UNUSUALEXT:Y (UX) ■τBooting without QEMM If you want to boot your PC without QEMM's memory management, first reset your system. Use the power switch if necessary. When you hear a beep, hold down the Alt key until the boot sequence stops. If you are using QEMM's DOS-Up feature, you will see a message asking if you want to unload the DOSDATA device driver; press Esc to unload it, then ■Φimmediately ■µ press and hold down Alt again until you see: "QEMM: Press ESC to unload QEMM or any other key to continue with QEMM." Press the Esc key. QEMM will not load, so programs will not load into High RAM, but your system will be usable. ■τContacting Quarterdeck Technical Support As a registered owner of QEMM, you are entitled to 90 days of free technical support. You can receive support by fax, mail, or phone. If you have a modem, you can get support through Quarterdeck's BBS, or through several other public message forums. Your 90 days of free support starts with your first call, letter, fax, or online communication in reference to QEMM. Before contacting technical support, we encourage you to see Appendix A of the QEMM manual for troubleshooting information, and Appendix B for a list of technical bulletins (technotes) included with QEMM. You can view technotes with QEMM Setup by selecting "View QEMM hints technotes and READ.ME" at main menu. ■τContacting Quarterdeck Technical Support (Continued) The troubleshooting guide and the technotes give step-by-step solutions to several common problems users may experience after installing QEMM. Also, be sure to see the file READ.ME in the \QEMM directory for late-breaking information. You can also view the READ.ME file with QEMM Setup by selecting "View QEMM hints technotes and READ.ME" at the main menu. For information on contacting technical support see the Passport booklet included with QEMM or read the text file CONTACT.TEC located in the \QEMM\TECHNOTE directory. To read that file, view it in a text editor such as EDIT, provided with DOS 5 and 6, or load it into your word processor as an ASCII file. ■τContacting Quarterdeck Technical Support (Continued) Quarterdeck also offers extended support, priority support and corporate support plans. See the Passport booklet for information. ■τSwitching Between MS-DOS 6's Memory Manager and QEMM QEMM provides all the functionality of MS-DOS 6's memory manager, and much more. For a list of QEMM's features and how they stack up against DOS 6's memory manager, see "QEMM Benefits and Features" in Chapter 1 of the QEMM manual. If you are using MS-DOS 6 and you have run its MemMaker memory utility, you can switch back to QEMM by running QEMM's Optimize program (assuming you have already installed QEMM on your hard disk). To run Optimize, type OPTIMIZE at the DOS prompt. If you ever want to switch back to MS-DOS's memory manager, simply run MemMaker again. If you are using QEMM's DOS-Up feature, be sure to run QSETUP and disable DOS-Up before you run MemMaker. ■τSwitching Between MS-DOS 6's Memory Manager and QEMM (Continued) If you are using QEMM's Stealth DoubleSpace feature and you decide to switch back to MS-DOS 6's memory manager, the ST-DBL.SYS driver will perform the same function as DOS's DBLSPACE.SYS /MOVE. That is, it will allow DBLSPACE.BIN to be moved into upper memory. You can replace ST-DBL.SYS with DBLSPACE.SYS, but you will suffer no ill effects if you do not. ■τQEMM Technote Index You can view the following technotes, in the \QEMM\TECHNOTE directory, by pressing the corresponding number: 1 = MS-DOS 6 and Quarterdeck Products 1»TECHNOTE\MSDOS6.TEC 2 = DOS 5 and Quarterdeck Products 2»TECHNOTE\DOS5.TEC 3 = DR DOS 6 and Quarterdeck Products 3»TECHNOTE\DRDOS6.TEC 4 = MS Windows 3.1 and Quarterdeck Products 4»TECHNOTE\WIN31.TEC 5 = DESQview/X: Maximizing Window Size 5»TECHNOTE\MAXWINDO.TEC 6 = Classic DESQview: Maximizing Window Size 6»TECHNOTE\WINSIZE.TEC ■Φ--- Type the number of the item you want --- ■ΦPress PgDn for more ■τTechnotes (Continued) 1 = Using Bus-Mastering Devices 1»TECHNOTE\BUS-MAST.TEC 2 = Disk Compression: Stacker 2»TECHNOTE\STACKER3.TEC 3 = Disk Compression: SuperStor 3»TECHNOTE\SSTOR.TEC 4 = Disk Compression: DoubleDisk Gold 4»TECHNOTE\DBLDISK.TEC 5 = Disk Compression: XtraDrive 5»TECHNOTE\XTRADRV.TEC 6 = QEMM: General Troubleshooting 6»TECHNOTE\TROUBLE.TEC 7 = QEMM: Advanced Troubleshooting 7»TECHNOTE\QEMMFLOW.TEC 8 = QEMM: Analysis Procedure for Memory Conflicts 8»TECHNOTE\EXCLUDE.TEC 9 = Solutions for Problems with Specific Products 9»TECHNOTE\PRODUCTS.TEC ■Φ--- Type the number of the item you want --- ■ΦPress PgDn or PgUp for more ■τTechnotes (Continued) 1 = Microsoft Windows 3.x Advanced Troubleshooting 1»TECHNOTE\WINFLOW.TEC 2 = Exception #13 Errors Explained 2»TECHNOTE\EXCEPT13.TEC 3 = Exception #13 Advanced Troubleshooting 3»TECHNOTE\EX13FLOW.TEC 4 = Stealth ROM Technology Explained 4»TECHNOTE\STLTECH.TEC 5 = Stealth ROM Troubleshooting 5»TECHNOTE\STEALTH.TEC 6 = The "Disabling Stealth ROM..."
