BCM Diagnostics for DOS, Version 1.01.07 Copyright (c) 1996-97, BCM Advanced Research, Inc. Tel: 714-4701888 Fax: 714-4700883 E-Addr: Tech_Support@BCMCOM.COM BCM diagnostics utility, DOSDIAG.EXE, is a DOS based program designed to help you evaluate your system's motherboard or identify problem causes in the event of motherboard malfunctions. This program has been tested sucessfully with many newly released Intel Pentium, Pentium Pro, Pentium II, AMD K5, K6 and Cyrix 686 motherboards, hoewever if you still encounter problems related to compatibility issues, please let us know. Notes 1. This program is best run under a clean-boot DOS environment either in floppy or hard disk with a mouse or without. Under DOS, DOSDIAG is able to access hardware directly and bypasses OS layer. Thus, hardware related problem can be detected more precisely. The DOSDIAG also runs under Win95 command prompt or DOS mode, but not under Win95 or Window 3.1 DOS box. The BCM Diagnostics for Win95 has a built-in short-cut to run DOSDIAG. 2. For burn-in test, this program can be run without user interface. Type DOSDIAG /? for instructions. If /T or /t is to be used to run selected test(s) in command mode, a DIAG.INI file needs to created first. Use space-bar to tag each selected test. A left arrow mark indicates test being selected. After all selected tests are tagged, exit program and DIAG.INI file will be created. Use "DOSDIAG /T" to run all selected test(s) in batch mode. 3. The Modem Test within serial port test is tested only with limited types of modem, such as modem with Rockwell chipsets. If you have a Plug and Play modem, it may not be enabled or initialized properly under DOS. Thus, DOSDIAG may have problem detecting your modem. Anyway, if you encounter modem problem with other chipsets, please let us know. 4. The Sound Test only works with Sound Blaster or compatible card. PNP sound card needs to configured with manufacturer's driver before test. 5. If you are using a serial port mouse to run Serial Port Test, you may lose mouse after test is done. 6. Loopback Connector Diagram: a. Serial Port: 1 -- 4 -- 6 2 -- 3 7 -- 8 -- 9 b. Print Port:(*note) 1 -- 13 2 -- 15 11 -- 17 10 -- 16 12 -- 14 (*note):ECP,EPP or Bi-Dir is required for loopback test. 7. For the factory, production, or burn-in environments: The switch "i" can be used on the following modules: SYSBRD.EXE, VGAT.EXE, BMEM.EXE and CDROM.EXE to force DOSDIAG to compare the current system to a known configuration. The Options menu can be used for the same purposes as well. Mark the options that need to be checked, and DOSDIAG will report error(s) if any deviation is found. For example, SYSBRD.EXE can be set to always check for the presence of the PS/2 mouse. This is done by generating an check file, "SYSBRD.CHK", by typing "sysbrd i" at the DOS command prompt. SYSBRD.EXE checks for the presence of this CHK file; if found, SYSBRD.EXE assumes the PS/2 mouse is installed and BCMDIAG will fail if it cannot detect it. For VGAT.EXE, the size of the video memory can be defined by generating a CHK file (type "vgat i" at the command prompt.) If this is done on a 2MB Video Memory configuration, a board which only has 1MB will be reported as a failure. For BMEM.EXE, the size of the system memory and secondary cache memory can be defined (type "bmem i" at the command prompt.) If this is done on a system with 16MB RAM and 256K cache, any deviation from this configuration will be reported as a failure. For CDROM.EXE, the presence of the CDROM.CHK file will cause CDROM.EXE to report error if no CD-ROM drive is detected. 8. F4 key is used to entry test loop count to run all tagged test(s), and F5 key is used to run all tests.
