I have a Center Pro with an Adaptec card and I'm trying to run MkLinux. I can't get MkLinux to recognize the drive on the Adaptec card. If I move the hard drive to the main logic board SCSI bus it works fine.
DISCUSSION
There are 3 possible solutions for this problem. The first two should work fine, but have some drawbacks. The third may or may not help.
1. Move the existing hard drive to the internal, non-Adaptec bus. Termination will need to be changed to off and the drive will need to be installed between the logic board and CD drive. That should make MkLinux happy, but you lose the speed benefit of the Adaptec.
2. Get a secondary hard drive, set it to ID0 or ID1, termination off, and put it in place between the CD-ROM drive and the logic board on the SCSI chain. Run MkLinux from the secondary hard drive. Again, you lose the benefit of the Adaptec's speed, but MkLinux is happy and your main hard drive still benefits from the Adaptec.
3. The third thing that may help is moving the Adaptec to a different part of the riser. Normally, PCI slots come in 3s, but PCC tweaked the Center Pro riser and logic board to accept a 4th slot. The extra slot is the ATI RAGE circuitry built into the riser which is why it still looks like there are just 3 slots. We did the same thing to the PowerBase. The RAGE circuitry controls your video. Logically, it's the first slot in the system. In some of the Center Pro configurations, the Adaptec card is in "slot 4", nearest the logic board, which may be throwing MkLinux for a loop. You can try moving the Adaptec to one of the other 2 slots to get it into the normal 3-slot configuration. MkLinux may then be able to recognize that there's a controller there and a drive. This really is a major longshot, and there are no guarantees that this'll help
