A Guide to Building a PC with an AMD Athlon™ Processor
Using UDMA/66 (ATA-66) or UDMA/33 (ATA-33) Devices
Q. Can the AMD Athlon processor-based systems be used with UDMA/66 (ATA-66)
devices (i.e. hard drives)?
A. Yes. The UDMA/66 capability of your motherboard is contingent on three factors:
n Your motherboard supports UDMA/66
n You are using a UDMA/66 device
n You have the newer UDMA/66 cable
If the wrong cable is used, you will experience corrupted installations and loading
of programs, system lockups, and various other types of failures.
If you are using UDMA/33 (ATA-33) devices, your motherboard will automatically
default to UDMA/33 (as long as the motherboard supports UDMA/33 as well).
Installing the AMD Athlon™ Processor on the Motherboard
Q. Is there any special way to install the AMD Athlon processor on my motherboard?
A. Yes. Refer to the AMD Athlon Processor Installation Guide that comes with your
AMD Athlon Processor-in-a-Box product.
Installing IDE and Diskette Drive Cables
Q. How do I install my IDE and floppy drive cables on my motherboard?
A. Most cables supplied by motherboard manufacturers have a tooth or key in the
center of the end of the cable connector that matches up against the notch cutout
on the connector end of the device you're hooking the cable connector up to (i.e.
hard drive, CD-ROM, etc).
If there is no key on your IDE or diskette drive cable, use the red stripe located on
the side of the cable as a guide. The red stripe should correspond to pin one on the
cable connector. The pin number location is printed on the motherboard.
