I have a dell XPS T450 currently running BIOS version A04 and I was thinking about upgrading the bios the latest version. The currently it has its stock cpu a p3 450. I was hoping to put a Pentium 2 233 to see if I could get better DOS compatibility but when I tried to boot with it installed I got nothing. After reading up a bit on other forums it looks like this motherboard should support a Pentium 2, or even a Pentium 3 up to 1GHZ with a bios update so long as the FSB is 100MHZ. So my goal would be to swap out the p3 450 with a Pentium 2 233, and potentially a Pentium 3 in the 600-900 MHZ range.
The number on the motherboard is
0005335T-12461-98A-009S
AA 722394-109
And I'm pretty sure this is the motherboard it has

These are the BIOS files I could find but I have no idea if these are correct. It specifies that this bios is for the R not the T series.

The one I think would work from this list has the following name and is towards the bottom of the list.

Do you think any of these BIOS files would work? I would hate to brick this awesome machine. Thank you so much for your time and responses.
