- SHOWSET & Related Files - (C) 1991 Micro Firmware Inc.
-
- The ShowSet program, documentation, and related files may be freely
- distributed so long as all the files are distributed together and
- unmodified.
-
- ShowSet is periodically updated, and the updates can always be
- obtained from the Micro Firmware Product Support BBS, which can be
- reached at the following numbers:
-
- 300/1200/2400 BPS ........... 405-321-2616
- 300/1200/2400 BPS MNP ....... 405-321-2400
- 300/1200/2400/9600 V.32 ..... 405-321-3553
-
- Connect with 8-bit word, one stop bit, and no parity.
-
- ===========================================================================
-
- As of version 1.74, ShowSet should be able to identify systems running
- standard implementations of the following chip sets:
-
- Acer
- * 1207
-
- Chips & Technologies:
- * CS8221 (NEAT)
- * CS8230
- * 82C235 (SCAT)
-
- Headland Technology:
- * HT113
- HT21
-
- Intel:
- * 82335
- * 82340 (same as VLSI VL82C286)
-
- OPTi:
- * HiD/386 or HiB/486
- Cache Sx/AT
- * 386WB
-
- Sun Electronics:
- * Suntac
-
- VLSI Technology:
- * VL82CPCAT-16/20 (enhanced)
- * VL82C286 (TopCat)
- VL82C386 (TopCat)
-
- Those marked with an asterisk ("*") have been verified as being correctly
- identified on an actual motherboard. The others are only based on information
- (sometimes preliminary) of how the chip set should behave and has not yet
- been verified against an actual implementation. I would appreciate any
- feedback on the results of running ShowSet on a computer using one of the
- currently unverified chip sets.

- 11/21/91
- Changes introduced in version 1.74:
-
- ShowSet now differentiates between different versions of the SCAT
- family.
-
- The VLSI TopCat chip set test caused ShowSet to lock up
- on an 80486-based system. This has been corrected.
-
- ShowSet can now better differentiate between different Headland
- Technologies chip sets.
-
- 10/6/91
- Changes introduced in version 1.70:
-
- ShowSet now warns that the system may need to be rebooted after
- it is run. If run on a '386 or above, it also checks to make sure
- no 32-bit memory managers are active.
-
- ShowSet also does some memory timing testing and analysis and
- will attempt to determine the width of the BIOS ROMs. If the
- system is using an unknown chip set and the BIOS is shadowed,
- this feature will not work (ShowSet would be calculating the
- shadow RAM width instead) and ShowSet will report its inability
- to test this. If ShowSet can identify the chip set, it will
- automatically disable any shadowing for the duration of this
- test.
-
- In addition, several command line options are now supported:
-
- /H - Supresses all the hardware related testing. This
- is the "safe" mode of operation; it can be run
- under most multi-tasking environments without grief.
- For most accurate results, however, you should run
- ShowSet without any other programs or device
- drivers loaded and not use the /H option.
- /W - Supresses the warning message.
- /L - Lists current chip set detection support. Handy if
- SHOWSET.COM gets seperated from this documentation.
- /R - Displays the chip set's registers in the form xx-yy
- where xx is the register's index and yy is the
- current value in the register. All numbers are in
- hexadecimal.
-
-
- 9/29/91
- Changes introduced in version 1.61:
-
- ShowSet was internally restructured to be more managable.
-
- Corrected a problem in which ShowSet would sometimes incorrectly
- claim that the BIOS indicated a chip set named "Advanced".
-
-
- 6/26/91
- Changes introduced in version 1.60:
-
- ShowSet now scans the system BIOS in an attempt to locate
- a chip set name. This will help identify chip sets that
- ShowSet does not currently know how to test for and/or
- chip sets that might be otherwise undetectable (such as,
- in some circumstances, Intel's 82335 chip set).
-
-
- 3/5/91
- Changes introduced in version 1.50:
-
- The Acer 1207 and Chips & Technologies SCAT tests were added.
-
-
- 1/24/91
- Changes introduced in version 1.42:
-
- In some implementations, due to a perculiarity in the address
- decoding, VLSI Technology's VL82CPCAT-16/20 (enhanced) chip set
- was not always recognized. This was corrected.
-
-
- Changes introduced in version 1.41:
-
- The OPTi tests would identify Chips & Technologies chip sets
- as an unknown OPTi. This was corrected.
-
-
- Changes introduced in version 1.40:
-
- Tests for OPTi's chip sets were added.
-
-
- Changes introduced in version 1.30:
-
- The Suntac test now leaves the EMS base port address in its
- original locatation. Because of an oversight in changes made in
- version 1.20, the EMS base port address would get moved to E8h
- if the power-on location was 98h
-
- Tests for CS8220, VL82CPCAT-16/20, and VL82C386 were added.
-
- Internal organization was restructured and optimized somewhat.
-
- The architecture tests were made a bit more stringent. Some
- XT semi-compatibles were being identified as being an XT.
-
-
- Changes introduced in version 1.20: (initial release)
-
- Tests for machine architecture (PC, XT, AT, or other) were added.
-
- Tests for 82335 and VL82C286 were added
-
- The Suntac test was changed to deal with the EMS base port address
- being at a non-default location.
-
- All tests were updated to deal with the data bus "floating". On
- some motherboards it was found that reading from an undefined port
- would return the last value transfered on the external data bus.
