: I recently upgraded my computers bios and since that my video editing card does not work and pci-s are not functioning correctly.


Before you go back to the mainboard maker's web site to find an earlier BIOS some suggestions are:
1. Confirm that you actually updated your BIOS - sometimes it is possible to save the BIOS then flash with the old bios - check current BIOS date, version and checksum vs what you started with and what you are expecting based on BIOS release notes. You are probably OK, but no harm being certain.
2. Download and install ALL OS patches that you csn find.
3. Download and install the very latest drivers you can find for your mainboard features and expansion cards (eespecially video); look for bus mastering and anything to do with PCI bus - check the chipset maker's web site, too - sometimes they post generic updates before the board maker (they usually work but you'd miss any "custom features" inserted by the mainboard maker).
4. Make sure your CMOS Settings are "right". After BIOS flash you MUST CLEAR CMOS, enter CMOS Setup, set date and time, detect IDE devices, choose "default", "optimal", "fail safe" or any other standard setup, SAVE settings and exit. Do this again - there may be some flash trash remaining in Setup.

See how all of that works out - updated OS and drivers fixed a bunch of similar problems for me a few years ago. You MAY have an odd setting in CMOS Setup that is now affecting your video - maybe a default setting is different now - you will need to look for anything that looks odd or doesn't agree with your preflash CMOS Settings (you DID write them on paper, didn't you - I didn't either the first time!). If your screen is OK while you are in CMOS Setup but goes bad after boot - suspect a CMOS Setting. I have a mainboard that was working fine, updated BIOS to use large HDD - now the screen is unreadable unless I disable video BIOS shadow in CMOS Setup. If you experiment with deviations from a standard setup you can always get back to the starting point.

5. Check your BIOS update diskette - you may have saved a copy of the old BIOS - if so, you have your backdate already.

Hope some of this helps,
Henry
