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.
