Hello all,

It seems the links on Microsemi's website have finally broken and many downloads are no longer available. I don't know if/when they will be restored, so I'm hoping the community can help out.

I have an Adaptec 2940UW with BIOS version 1.25. I was able to locate the latest BIOS version 2.20 on TheRetroWeb.com, but I can't seem to locate the BIOS update utility to flash the BIOS. Does anyone have this software they can share with me and others? I would like to update the BIOS to see if it resolves a compatibility issue I'm having with a Micronics motherboard.

Thanks in advance and sorry if I posted in the wrong area!

FYI Microsemi / Adaptec maybe close to removing downloads for their older products - call to action

Thanks! I did not see that thread and I'm happy to see the community has already jumped on the problem. I'll post my request in that thread.

I believe that's it! I'll verify once I get home after work.

The latest 2940UW BIOS is 3.10. It adds support for larger drives. You can find it in this thread:
