Soyo SY-5SSM won’t recognise HDD’s

Locked

I have just purchased a used Soyo SY-5SSM motherboard to replace my old one when a BIOS update went wrong. After installing everything I booted up and went into BIOS and it refused to recognise any of my HDD’s drive on IDE1 but it recongised my CD ROM drives on IDE2. If I swap the cables around it still won’t recognise the HDD’s. I put a DOS floppy in and it recognised Drive A; and also Drive B: but I only uhave 1 FDD.
I also purchased a Biostar M5VNB motherboard so I put everything on this one and on the first boot it recognised everything.
Is the Soyo motherboard faulty or is a BIOS update required. How can a motherboard be tested?

Since the board recognizes your CD-ROM drives, it appears to be functioning.

How large are the hard drives?

It is possible that the motherboard has a limit as to how large of a HDD it can recognize.

Soyo does have a BIOS update that was released in 2000. Revision 5ssm2db1
If you decide to flash the BIOS, follow ALL precautions listed on the BIOS download page.

1 other thing to check, enter BIOS setup and make sure that all 4 IDE device channels are set to auto-detect.
Being used, it is possible that someone set the device types for the specific drives they were using. Or, even set all unused channels to none.

I would reset the CMOS using the jumper on the motherboard. The correct procedure for doing so is in the manual if you don’t have it download from SOYO’s website. This way you don’t have to worry about previous settings that may not match you hardware and needs. This will also set the IDE channel to auto-detect mode. The reason the second motherboard worked is because when you firat buy a new board the BIOS is on factory default.
