computer doesn't recognize primary slave on cold boot

[chipb]

I've got a Soltek motherboard with a AMD K-6-400 cpu and a Award 4.51 PG BIOS. My machine also has two IDE hard drives configured as primary master and primary slave, a cd-rom, and a floppy drive. On a cold boot, the computer does not recognize the primary slave hard drive. However, on a cold boot, if I go into BIOS setup and immediately exit without making any changes, the primary slave will get recognized. Also, the primary slave will get recognized on a soft boot. I suspected that my my power source might not be large enough so I hooked up a 250 watt power source (I normally have a 200 watt power source) but this didn't solve the problem. Any suggestions?

I've seen this happen before and it took me awhile but I solved it. Turn off fast boot in the BIOS.

If the Master drive is significantly faster than the slave drive like a 7200rpm with a 5400rpm slave what happens is the slave drive doesn't have adequate time to spin up.

The master drive works fine. Sometimes the extra few milliseconds gained by turning off fast boot in the BIOS will help. The other solutions are to make the slower drive master or put them on seperate IDE channels.
