Since I upgraded the BIOS some programs will not run. The new BIOS is PhoenixBIOS 4.0 Release 6.0. Installing it took the BIOS version from A4 to A11. First off, I would like to downgrade the BIOS to something between A4 and A11. The problem is finding any site which provides old versions of a BIOS. Secondly, I understand that Phoenix recently issued Release 6.1 and I would like to try using that to solve my problem but again I cannot find a site where I can download it.
This is the latest BIOS released for this motherboard click here - it doesn't tie in with the versions you gave.
I would caution you strongly against using BIOS versions from anywhere other than the motherboard manufacturer. It often happens that manufacturers customise BIOSs for their boards, making them different from the BIOS suppliers "standard" version.
Stuartli and DieSse, Many thanks to you both. I tried all the sites provided by by Stuartli and the best was the Intel site. The link provided by DieSse also took me to the Intel site where I downloaded the latest upgrade for my motherboard. I ran this but the result was exactly the same as the BIOS I was already running (originally downloaded from the Dell site). Thus my BIOS still shows the OS as Win98 instaed of Win98SE. I appreciate the point made by DieSse about the dangers of using the BIOS supplier's version but I would like to try version 6.1 from Phoenix as neither Intel nor Dell provide that version yet.

It isn't the BIOS that shows your OS as anything - the BIOS doesn't do that. I'm not even sure whether Win98SE is specifically identified by systems anyway - perhaps someone else can answer that - but why does that matter?
