Summer '94 Yggdrasil will not boot on my PCI-based system with a Media
Magic ISP-16 soundcard (supposedly Soundblaster-compatible) with
attached Sony CDU-33A CDROM (after initialization, it panics with
"Unable to vfs_mountroot"). In addition, while it detects the NCR
SCSI card, it doesn't recognize the hard disk (Seagate ST14200 2.1 GB)
on target 0 (it says 0 hard disks, 0 CDROM's, 0 total devices).
