Blue & White & SCSI & Ultra 2 SCSI & Kernel > 2.2.10 -> No Disk s

[Michel Lanners]

On   8 Apr, this message from John Doty echoed through cyberspace:
> My Yosemite G3 (Rev 2) has *two* SCSI cards: an Adaptec 2930CU, and an
> Adaptec 2940U2B (Ultra 2 Wide). Last summer, my son Matt (who

Isn't this the OF resource assignment problem discussed here some time
ago? Have a look at the mailing list archives...
