pci0 at nexus
itpsa0 at pci0 slot 7
Checksum read error.
*** Attempt to run on unsupported adapter ***
itpsa0 not probed

psiop0 at pci0 slot 7
siop_pci_initialize: Warning - Using unsupported 53c875 scsi chip
Loading SIOP: script c0001b00, reg 82011000, data 4094fa98
scsi0 at psiop0 slot 0
rz0 at scsi0 target 0 lun 0 (LID=0) (IBM DDRS-34560D DC1B) (Wide16)
rz4 at scsi0 target 4 lun 0 (LID=1) (TOSHIBA CD-ROM XM-3301TA 2411)

What can I do to install NetBSD 1.4 on it?
