This is kind of continuing my earlier post. I have a motherboard. I plugged in graphic card in the AGP, and connect the motherboard to a floppy drive(This drive works well on another machine). I inserted a Windows98 disk(It boots another machine well) and change the BIOS to boot from the floppy drive. I reboot the system, can hear and see the floppy drive is reading the disk. However, the system can not boot up. Only the graphic card and floppy drive connected to the motherboard(no hard drives, no CDRW or other peripherals) Accoding to the above, can I say this is a bad motherboard? Thanks a lot!
