To clear the CMOS memory and your
password:
- Turn off your system.
- Unplug the speaker cable from
the riser card and plug it in upside down.
- Turn it back on, wait for memory
to count, and listen for the beep.
- Turn the system off, and plug
the speaker cable right side up again.
The password will be cleared.

is the name for the PS/2 news group?

We now have a sound solution for
microchannel computers! The card is 100% Sound Blaster compatible
with DOS, Win3.1, Win95/98, and OS/2. It features the latest in
advanced DSP technology and comes with some great software. Now
you can enjoy the all the features of your multimedia, presentation,
games, music, and entertainment software.
The ADF file for a microchannel
card may not be on your reference diskette.
Whenever you add or remove a microchannel
adapter card you will need to run the reference disk and configure
the system. During the configuration process the system wants
to have information on the new adapter card. This information
is in the form of a file with an ADF extension (such as @1234.adf).
The file is normally supplied by the manufacturer, on a diskette,
with the adapter card. The ADF file is unique for each adapter!
When you move the card from one
computer to an other or even from one slot to another you will
need to run the reference disk to reconfigure. The ADF for
that adapter must be on the reference disk or the system will
beep twice and display a 165 error on the next startup.
The problem you may find is locating
an ADF file for your card. If it is an IBM card and you know what
kind of card it is, you can download it from IBM ftp site (see
question #8). If it is made by another company try going to their
web site and download it, if possible.
See question 9 and 10 for additional
information on downloading ADF files.
All VGA monitors display colors
in an analog manner. In other words, the monitor can display an
infinite number of colors, but the controller card, which is digital,
is dependent on the video memory. The standard VGA controller
had 256k of video memory and was limited to 16 colors at 640x480
resolution. Our DS301 IBM XGA2 adapter
has 1mb video ram and will display 256 colors at 1024x768, 800x600
and 640x480 resolution. If you have a standard VGA monitor you
probably will only be able to select 640x480 which is fine for
OS/2 Windows and Windows95/98.
There are two factors that affect
speed of memory. One is the actual "speed" of the chips
and the other is called "presence detect." Most chips
are 60ns. A 60ns chip is designed to run at 60ns, but through
a set of resistors (presence detect), the SIMM can be re-configured.
Presence detect governs the size of the SIMM (4mb, 8mb, 16mb,
etc) as well as the speed in which the computer will access the
memory (60ns, 70ns, 80ns, etc.). Even though the chips may be
rated at 60ns, the presence detect resistors control how the computer
sees this memory and will use it. With some systems, such as IBM,
it is imperative that you have the presence detect set correctly,
otherwise the system will not function properly or perhaps fail
to recognize the memory at all.
IBM has ADF files for IBM microchannel
cards on their FTP site. The easiest way to locate the file you
are looking for is to first download a file called ALLFILES.TXT.
Using a text editor, search the descriptions to find the filename
of the ADF file you need. You will notice that the list is divided
up into categories, such as "Reference & Adapter Diskettes."
Just below the category is its sub-directory name such as "/pub/pccbbs/refdisks."
Then go to IBM's
FTP site and click on that sub-directory to open it. You can
right-click on the file name to download it if you are using Netscape
or Microsoft Explorer.
One very good source for ADF files
of older, non-IBM, microchannel cards is at NCR's
web site.
You must see Peter
H. Wendt's Web site and download excellent and free software
that will identify a microchannel controller and also give you
the ADF file name. Peter has a very large collection of ADF files,
all grouped in ADF file name order.
When the system has more than one
beep on startup it will display one or a series of numbers. The
numbers are called Error Codes. For a very complete list of the
PC and PS/2 error codes see The
PS/2 Error Codes Page . Credit goes to the Microchannel
Entusiasts Page.
You can download the file SCSICDRM.EXE
from the IBM ftp site .
