Basically, none of the drives (HDD or CD) are being detected on a computer I'm working on. In the BIOS it just has "not detected" next to all the drives (ie, Primary IDE Master, Primary IDE Slave, etc), and all the settings for the drives are set to "auto". The only thing listed in the boot sequence is "1st Floppy Drive", although there's no floppy drive installed. I also sometimes get a "CMOS battery low. CMOS date and time not set. Press F1 to enter setup" message when the computer boots.
I've tried resetting the BIOS (by both replacing the battery and with the jumper pins) using a different HDD, using different IDE cables, and using a different PSU, but none of it has worked.
Here's the specs:
Motherboard: ECS GS7610 Ultra (SIS 761GX+956L chipset)
BIOS: AmiBIOS v02.59
CPU: AMD Athlon 64 3000
Memory: 2x 512MB PC3200 DDR RAM (M2G9J16A-TT from TwinMOS)
HDD: Maxtor 6L200P0
PSU: COLORS-it EN60950
Now, since I'm just the guy trying to fix it and not the owner, I don't know the full history of the machine, but this is what I do know:
Machine gets brought in, rapidly switching on/off when you try to turn it on. One of my colleagues decides to try replacing the mobo and CPU. Problem persists, and I try putting in a new PSU. The problem clears up, but now we're left with the current issue.
PS: The next time I have access to the machine after today is going to be on the 27th, so I won't be able reply on what help did/didn't work till then.
