hi folks,

i encountered a strange problem with an old pc of mine, which i want to turn into a dos-box to run my old games again.
i replaced the original 486-mb with an microstar ms5117 ver2 motherboard (award 4.50pg) and a pentium 75, which i overclocked to 90mhz. first everything worked fine. later when i replaced the processor with an 166mhz p1 and upgraded the memory to 64mb edo, i got this strange error: the pc runs fine through all post tests and shows the system configuration screen. right when it should boot from hdd or fdd, it freezes and leaves me alone with a blinking cursor.

i tried numerous bios-settings and hardware configurations, but the problem remains. even when i put the p75 back in and reduce the mem to the original size of 24mb non-edo.

thx for help,
pavel

Try clearing CMOS.

Try disconnecting the HDD and removing all cards except VGA.
BTW.: What's the BIOS ID?

thx again, i tried it, but it had no effect. i even tried 2 different floppies and 2 different hds, 4 different sets of ram and 4 cpus, but nothing.

Disable L2-Cache and reduce FSB from 66 to 60 or 55/50 Mhz and test again .
