Try adding mac53c9x=1,0 to the command line in Penguin. This should solve your problem with installing from CD. It disables disconnects in the SCSI driver. SCSI-I devices cause problems with the NCR53C9X controller (used in the '040 Macs) when they disconnect so the driver doesn't allow disconnects for SCSI-I devices. The same type of problems were noted with SCSI-II devices (most notably the early Apple CD-ROMs) on some '040 Macs so the mac_esp driver was modified to take a command line parameter to turn off disconnects entirely.
