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.
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 full specs on the MI151 Sound Card are available,
including a photo.
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
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
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
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 on the PC and PS/2
error codes see our error code list..
You can download the file SCSICDRM.EXE from the IBM
ftp site .
Go to the General Technics driver download page.
