K7T266 Pro2U Not Booting

[buttasuperb]

Hello,

I recently got a MSI K7T266 Pro2-RU motherboard and an AMD XP2000+ processor. When I turn it on, I get the 4 red lights and no boot. I flashed the bios with the newest version, and it still won't work. I read in the bios history that 2000+ is supported, so I have no idea what's going on. My old 1ghz tbird works fine with the motherboard.

I run Win 2000
Radeon 9800 pro (actually just installed it along with the processor)
PC2100 DDR 256 (x2)
3 HD's (2 40gb are raided, other is 20gb)

Any help is appreciated. Thanks.

Uhm question? Please don't take offence, but how can you flash the mobo BIOS if the PC isn't booting ?? Or am I missing something ?

I one time experienced a strange situation with swapping to a newer CPU. I had TBred 2700+ and U/G'ed to a Barton 2500+ in my EPoX 8K3A+ mobo. Absolutely no other changes, even same HS/Fan. System did not boot. Tried all kinds of things... what eventually worked was to pull all devices that drew power except CPU/HS/Fan and vid card... booted okay, reconnected HD, rebooted okay, reconnected sound card, rebooted okay, reconnected LAN... etc., etc. until all components were added back.
Once the whole thing booted up, I've never had a problem. My guess was beats the Hell out of me! Maybe something to do with the "shock" of a large power draw on the PSU -- after clearing CMOS -- by hitting it with all the hardware components at once??? AIK, this procedure worked for me.

Oh yeah, I later did upgrade the PS from an older Enermax 350 to an Antec Trueblue 480
