Well ECS boards do not last forever.
What do you see when you go into BIOS??
I assume the CD is Secondary Master.
How did you check the CD-Rom to prove it was OK?
Did you try the CD-ROM in the other PC? Swapping the CD-ROMs woulb be a first try before swapping HD.
Why did you flash the BIOS? John
ECS K7VMM+ Motherboard with AMD Duron does not recognize CD-ROM on boot up, although it does recognize the floppy, and the Win 98 SE boot disk does work. Cables have been checked, and so has the CD-ROM and they are OK. It stopped working before a new BIOS was flashed and it is still the same after. I tried swapping a good hard drive with a good install of Win 98 SE from another ECS + Duron machine of the same vintage, but it gets stuck looking for drivers on boot up, which I can not give it because it doesnt see the CD-ROM.
