Q: I got a WD 6.4GB hard disk drive and it will not work, corrupting my installation, and lot of other problems (I set it as a SLAVE), what is the solution?

Storage Device

A: It may be an ATA-33 or ATA-66 that the system BIOS does not readily recognize the drive as Mode 2, but Mode 5 instead. You will need to run ATA 33/66 Tool under Western Digital LifeGuard Tools (WD provided it on the WWW and in the diskette enclosed with all new drives). Please follow the instructions to run this tool. This will reconfigure the HDD to be a standard HDD and will work on any motherboards.

Q: I tried to get on-board video to work. I am able to boot the system with a PCI video card. Is my on-board video defective?


A: If your BIOS has On-Board AGP video enabled, then you may have a defective motherboard.
