I recently upgraded my bios from smi site and now my cpu which used to read AMD Athlon 2600+ 2083 MhZ, now reads AMD Athlon XP, 1250 MHz. Is there any way of reversing the upgrade to solve this problem ?.

After flashing a BIOS you need to walk thru all the settings & correct them as necessary. Your FSB has reset from 333MHz (166MHz freq) to 200MHz (100MHz freq)...all you have to do is change it back. There are also numerous other settings that should be checked.

I have scanned the motherboard with AIDA32 and it came up with the following report. Can you point me in the right direction to put things right based on this information. Motherboard Properties Motherboard ID 62-1021-009999-00101111-040201-VIA_K7$1AARK204A6712VMS V1.C 102104 Motherboard Name MSI KT4V (MS-6712) Front Side Bus Properties: Bus Type DEC Alpha EV6 Bus Width 64-bit Real Clock 100 MHz (DDR) Effective Clock 200 MHz Bandwidth 1600 MB/s Memory Bus Properties: Bus Type DDR SDRAM Bus Width 64-bit Real Clock 167 MHz (DDR) Effective Clock 333 MHz Bandwidth 2667 MB/s Chipset Bus Properties: Bus Type VIA V-Link Bus Width 8-bit Real Clock 67 MHz (ODR) Effective Clock 533 MHz Bandwidth 533 MB/s Motherboard Physical Info: CPU Sockets/Slots 1 Expansion Slots 6 PCI, 1 AGP RAM Slots 3 DIMM Integrated Devices Audio Form Factor ATX Motherboard Size 210 mm x 300 mm Motherboard Chipset KT400

I already told you what you need to do. You didn't need to run AIDA32. Are you not familiar with BIOS settings? If not, why did you flash the BIOS in the 1st place? What were you trying to "fix"? Here's what you'll need to do...get into the BIOS & go to "Frequency/Voltage Control" & change the following settings: Spread Spectrum = disabled CPU FSB Clock = 166MHz The rest can be left at AUTO. Save the settings & reboot.

Contact the mfg, they usually offer the previous versions of bios. I read it wrong and answer it wrong too. So get off my case you peanut.
