after flashing my BIOS from F2 in one step increments to F6 , I now find that I cannot reinstall windows XP Pro SP3 , is it possible to actually reverse this and go from F6 back to F2 ? ( windows reboots the system at 39 minutes showing -checked log file in DOS , no .inf files showing )
my pc worked ok , and I haven't changed any other items on the PC ,and it has worked OK for 3 months ( not connected to internet )
1) checked HDD with full manufactures ( Samsung 500 gig spin point ) diagnostic software , inc full surface scan - all tests pass ok - I know how to use DOS and all the partitioning devices in windows - also run Hirens disk , ran full disk wipe and disk returned to RAW
2) removed 1 stick of PC 800 RAM ( corsair )
3) all temperatures ok
4) sata HD cable / keyboard / mouse replaced
5) Ran pc from dvd drive with Puppy Linux - pc works for hours and is fast and stable - though this doesn't install anything to the HDD
6) no disk partition /full 500 gig used at present / ntfs used
7) ATI 4770 graphics card used from initial build -have used it to play full Wolfenstein game
also tried to install winhome sp2 and that stops at same point ,as does windows original xp disk from 2002
so , it works ok at installing the system at F2 ,now on F6 or F5 it doesn't
