- Dear PC-INFO user:
-
- As many of you are aware, it is my policy to furnish the users of
- PC-INFO who spent the time and effort to contact me directly with
- a personal copy of new releases. PC-INFO, Version 2.15 has just
- been released for limited distribution. Tandy 1000 & 3000 series,
- the Tandy 1400LT laptop, and their 80386 equipped 4000 as well as
- Data General/1, AST Premium 286/386, and some PC Limited machines
- are now recognized and correctly identified. In addition, PC-INFO
- now recognizes and correctly identifies the IBM XT/286 as well as
- the PS/2 Models 25,30 & 30-286,50,50Z,60,70 & 80 & the recent 386
- machine from AT&T, the 6386 WGS. Certain EPSON Equity,Toshiba lap
- top, NEC,and Sperry models, as well as the COMPAQ Deskpro 286 and
- Portable 286 have been added to the constantly expanding list of
- uniquely identifiable machines. Descriptions of the 3 1/2" disk
- drives have been revised to display both the nominal 720K & 1.4Mb
- capacity. The descriptions of 5 1/4" disk drives have also been
- improved. PC-INFO now recognizes and identifies Intel 80387 math
- chips. In addition, those machines having the letters IBM in ROM,
- or not specifically identified by manufacturer, but which have an
- AWARD, American Megatrend (AMI), ERSO or Phoenix BIOS will be now
- identified by PC-INFO as IBM compatibles. The recognition of RAM
- disks created by various device drivers has been improved so that
- they are no longer identified as 3 1/2" or 5 1/4" floppy drives.
-
- Partition sizes greater than 32 Mb created with either IBM PC-DOS
- or Microsoft MS-DOS Version 4.xx are now recognized and reported
- correctly by PC-INFO. Disk sizes and free space up to 999,999,999
- may now be displayed.
-
- Weitek 3167 numeric coprocessors are now recognized & identified,
- in additon to the more common Intel varieties.PC-INFO reports the
- presence of a Weitek NDP regardless of whether the INTEL 80387 is
- installed or not.
-
- Machines useing the signature 'IBM COMPATIBLE'in the ROM BIOS are
- now correctly identified as clones,rather than true IBM machines.
-
- The Disk Information screen will now handle those machines with a
- single floppy drive correctly. Rather than skipping drives A: and
- B: completely, it will now report the information about whichever
- logical floppy drive the floppy disk is currently inserted in and
- not omit the floppy drive as was done in previous releases.
-
- A help screen has been added, which explains the optional command
- line switches. It is displayed by entering either /? or /h on the
- command line when PC-INFO is invoked.
-
- The code has been revised to properly handle the case of a CGA or
- EGA board operating with a monochrome monitor. Identification of
- VGA boards has been incorporated in PC-INFO.
-
- It is now possible to force PC-INFO to treat the video adapter as
- either a CGA (80x25 color mode) or a MDA (80x25 B&W text mode) in
- the event that the program does not deal with your display system
- properly. See PC-INFO.DOC for additional information.
-
- A PIF file is now provided to facilitate the use of PC-INFO in the
- the Microsoft Windows (tm) operating environment.
-
-
- The program PC-IDENT.COM, which also reports the machine code (in
- hex), is used to locate and display ascii character strings found
- in ROM which match certain criteria as to character arrangements.
- These strings serve to identify the manufacturer and model of the
- computer being tested.

- Known Hardware/Software Compatability Problems
- =================================================================
-
- - 1 -
-
- Execution on systems running COMPAQ MS-DOS 3.31, equipped with a
- hard disk formatted and partitioned with this release of DOS, may
- cause drives D and above to be incorrectly reported as RAM rather
- than Fixed Disks. This appears to result from the method COMPAQ
- chose to use to permit partitions sizes larger than 32 Mb. Since
- I do not have current access to either a COMPAQ machine or their
- DOS 3.31, it's unlikely that I will be able to resolve this error
- in the near future.
-
- - 2 -
-
- There has been reports of PC-INFO hanging up on AST 386/20 & IBM
- Model 70-E61 machines. At this time, it appears that these hangs
- are due to a BIOS incompatability,but we have not confirmed this
- yet.
-
- - 3 -
-
- It has just been brought to my attention that when Quarterdeck's
- QEMM.SYS is loaded, the amount of Extended Memory reported under
- COMPAQ DOS 3.31 will actually include the Expanded Memory shown.
- Since I do not have any systems running Deskview (tm), again this
- is unlikely to be resolved in the near future.
-
- - 4 -
-
- Extended memory on systems running DOS 4.0 or later now have the
- amount of 'available' extended memory reported, rather than the
- amount installed. (This is consistant with the amount reported
- when a INT 16, function 88h is executed.) The amount reported is
- based on this BIOS interrupt which appears to report incorrectly
- on certain machines, including NEC APC.
-
- - 5 -
-
- Several software packages used to partition fixed disks do not
- properly set the media descriptor byte. This will cause PC-INFO
- to report a Fixed Disk as a RAM disk. Also, any disk which does
- not have the media descriptor byte set to indicate a fixed disk,
- whose size does not match any of the standard floppy disk sizes,
- and is less than 4 MB in size will be reported as a RAM Disk.
-
- - 6 -
-
- Certain model Toshiba laptops (such as T1000 built prior to 1988)
- will display 'Toshiba ??' in the machine type field since Toshiba
- chose not to include model information in the ROM BIOS then.
-
