As I wrote above: It was the same when I installed the XP2400+,
then I downloaded the newest BIOS, installed it, an now it boots with XP2400+ !
Which AD73 di you have ? The AD73-Pro or the AD73-Raid ?
Here's the link to the latest BIOS of AD73-Pro :http://www.dfi.com.t...AD73PRO0830.ZIP
"Support AMD Athlon 2200+,2400+,2600+ CPU."
An here to AD73-Raid :http://www.dfi.com.t...D73RAID0524.ZIP
... but as I see, there is no Support in the Bios of AD73-Raid for XP-2400+ ! They have only released a BIOS for AD73-Pro to support newer CPUs, so you have to live whith it, I think.
... but wait, here I found a Beta-Bios from 2003/02/11:http://www.dfi.com.t...S/6A6LVD4D1.BIN
"1.Add "Promise RAID control" function (to Disable/Enable onboard RAID) 2.To Support AMD thoroughbred CPU"
This may work for you, if you have the AD73-Raid !
