446143 2006-04-14 01:22:00 Hi hoping for a bit of help here .

I have just purchased a new MB (ASRock K8-combo z) and new CPU (AMD Sempron 3000) .
I have tried to get it going, but get a message that the Bios does not recognise the CPU, fatal error . I have downloaded an updated bios from the web, but cannot get the computer to boot off the floppy .

It just comes up with the same message (BIOS does not recognise the CPU, fatal error), and I cannot get to the BIOS setting up programme by pressing F2 or F11 .

446144 2006-04-14 01:33:00 What CPU did you get? a 754 pin or 939 pin??

If 939 it looks like 2.20 of the BIOS is needed (which may not be onboard at the mo), and which maybe why it cant detect the CPU.

If its a 754 2.30 of the BIOS maybe needed.

It depends on what the revision of the mobo is, by the looks of it. C D or E.

446145 2006-04-14 01:41:00 The CPU is a 754 pin. The BIOS is 1.3. I have download version 2.7.
The problem is that I can't get the MB to boot a floppy or get through to the BIOS setup utility. So I can't update the BIOS.

446146 2006-04-14 02:13:00 Been there before, a couple of times I had to drop an Athlon into the mobo to update the bios to one compatible with the Sempron chip .

Though you maybe able to reset the bios via the jumper, then on first boot flash it with the floppy .

Clutching at straws though . . . . .

446147 2006-04-14 02:46:00 Interesting! I think the store must have some responsibility here. They sold me the motherboard, CPU and ram. You would have thought they would have alerted me to this possibility. I'll visit them tomorrow and see if I can get them to sort it out. Shane (1677)
446148 2006-04-14 03:36:00 Its because the CPU is 64bit and the MB is only recognising 32bit Semprons. Yep, the shop will need to flash it for you. pctek (84)
446149 2006-04-14 19:52:00 hm......odd pretty sure I gotta combo board, (thats theone that has the extra slot to run a 939) and I just plugged a sempron 754 3000 into it and it ran perfectly.......what I suspect is maybe someone has jumpered the board for the 939 cpu ?...... drcspy (146)
446150 2006-04-14 21:36:00 Hi drcspy, nope all Jumpers seem to be in the correct position. Do you know what BIOS you are using? And is your Sempron at 64bit type? Shane (1677)
446151 2006-04-19 21:47:00 Update: Problem fix.

Shop updated the BIOS, as they should have before selling it.
Looks like they may have had to swap the CPU in and out to achieve this.

Thanks for your comments.

446152 2006-04-19 22:25:00 Well, no not all shops update BIOS'es (or should), before they sell their mobos.

The shop wouldn't have known what speed CPU you were getting.

I think, its because you brought a higher CPU, that the mobo couldn't handle.

And the only way to fix it, was to put a lower spec CPU in then flash to a BIOS update that could handle the CPU you brought, then replace the CPU you brought, and then flash it again.
