I am working on an older PC with a Supermicro P55CM motherboard. It has a AMI pentium*PNP ISA bios with date of 1996, and INTEL pentium 100mhz cpu.
At bootup the bios auto dectects the hard drive ok and the AMI bios system config display is followed by the messages: External cache type: pipline burst Lpt mode: normal
DISK I/O error Replace the disk and press any key..
If I bootup from a floppy, the C drive is allocated to ramdrive and then messages saying it could not detect Win 98 or virus etc. and it then shows the A: prompt
I ran Tufftest diagnostics and they ran ok. The hard disk boots up on other machines.
Got any suggestions, questions, etc.
