Is there so= me=20 voodoo in the BIOS of a Compaq machine that makes it work properly? I d= on't=20 have a Compaq machine, just the SmartArray card cabled externally to a=20 Proliant with everything disabled and unplugged except the power supply= ,=20 case fans, and Compaq array cages. The test results didn't change materially when I added another controll= er=20 (the promise Ultra 100 ATA). The docs say you can use both external connections if you don't use the= =20 inside ones, so I did that. I have a 5-drive hotswap cage cabled to one= =20 external connector, and a 3-drive hotswap cage cabled to the other. The third group is the Compaq array controller.
