HELP, Celeron 700 to 1000 Upgrade Windows 2000

[johnpr98]

I have a huge problem

My SuperMicro P6SBA motherboard can support a 1000 celron (The link is in my Win2K emails), My son has a 800 on his computer, Win 98SE

I can load Windows 98SE with no problems

I can't load Windows 2000

The Blue Screen errors are STOP C00026C Unable to load device driver.

I went up in 2000 Safe Mode & mrxsmb.sys device driver 0x000221 came up, In 98SE I moved this file out of Wint\System32 to a dump folder, my next start up attempt failed wit DRIVE_IRQL_NOT+LESS_OR_EQUAL, I then put mrxsmb.sys back where it came from.

I also get a DSP CPU microcode error on start up but this doesn;t affect 98SE, There is a CPU microcode Updation option mentioned in the BIOS manual, However it isn't in my BIOS

I have 2 options left unless someone knows more.

1) Reinstall Windows 2000 & hope that it sorts things out (If I can over SP2?)

2) Go back to my 700 Celeron

Help me please

Thanks

Are you trying to move your W2k drive to system with a different motherboard and hope rebooting W2K will have PnP figure it all out?

Won't work. MS also designed W2K so you can't re-install over and existing setup. This is a royal PITA but I've been told its for some C-level security (NT flunked here, you could boot a floppy and get access).

I posted a thread about upgrading my wife's W2K computer a bit over a week ago. The proceedure I used seems to work great, but she had no video editng software installed.

Thanks for your interest Wally, I will search for your previous thread.

All I've done is upgrade the CPU from 700 to 1000 (Which is possible I THINK

I can boot in 98SE fine, Win 2k Naye.

Win 2000 seems to have a problem with a changed CPU?

Cheers

I have tried to reinstall windows 2000 to my other spare partition, Blue screen time again
It may be that the BIOS upgrade isn't up to the task for Windows 2000 , even though 98SE is OK.

Very frustrating as I don't have access to my NTFS stuff.

If any other Win 2K gurus have any ideas I will be eternally grateful.

My tech is going to play the jumper detective game tomorrow with his supplier.

If its just a CPU swap to the same MB I've done this on W2K.

Shouldn't be a problem. Faster chips do push the limits of the regulators on older boards, sometimes it comes down to a point revision level on the MB silkscreen as to if the faster chip will work or not independent of any BIOS updates.

I've pretty much concluded that MB, CPU and Memory live and die as a uint during updates.

Just a quick note, the Err..BSP CPU Microcode error is a BIOS error. It is not usually too bad, but it can be fixed with the latest MB BIOS in most cases (if they have one). I had the same error for close to a year with no problems. Upgraded my BIOS one day and it was gone. No improvement in anything, just one less thing to look at during booting.

Assuming you jumpered your motherboard correctly (Bus speed at 100 MHz, PCI at 33.3 MHz, AGP at 66.6 MHz, Cpu voltage 1.7(?)
Volts):

There's one HUGE difference between a 700 and 1000 MHz Celeron and that's the bus speed.

That means that your RAM memory is now running at 100 MHz instead of 66 MHz. Your problem is almost certainly caused by Ram chips that don't run reliably at 100 MHz.

Are you sure you have PC-100 DIMMS in your motherboard? At what cycle (2-2-2, 3-3-3?) do you run them?

I'm back with my 700MHz Celeron
Super Micro tech support said today

P6SBA does support PIII up to 1GHz in "Slot1 type" if the onboard voltage controller is with new revision

It looks like my BX mb is an older one than my son's (Purchased 2 weeks later which has a 800 celeron working fine with Windows 98SE), This probably means my onboard voltage controller is an older revision which won't support above 800MHz. I can't prove this either way. as I can't read the writing on the chipset, even with the camcorder zoom.

My tech will make use of the 1000 celeron in another computer. I didn't really need the 1000 now but the price would have been OK for this upgrade.

I never realised how much I missed Win 2K, Now where's Internet Explorer 6
