Hi,

I have DEC AXP 3000/300L with DEC OSF/1 V1.3A. Here are more details:

DEC OSF/1 V1.3A (Rev. 113)
DEC3000 - M300 system
Firmware revision: 7.0
PALcode: OSF version 1.45

I have CD drive (Toshiba XM-5701) as rz1. Here is appropriate entry from
/var/adm/messages file:

rz1 at asc0 bus 0 target 1 lun 0 (TOSHIBA CD-ROM XM-5701TA 0167)

I would like to boot DIGITAL UNIX from CD with DU 4.0B to reinstall system.
Here is output of 'disklabel rz1' command:

# disklabel rz1
# /dev/rrz1a:
type: SCSI
disk: RZ56
label: T4.0B-r564_OS1
flags:

8 partitions:
# size offset fstype [fsize bsize cpg]

  f: 301986 997188 unused 1024 8192 # (Cyl. 1231*- 1603*)
  g: 819200 393216 unused 1024 8192 # (Cyl. 485*- 1496*)
  h: 86758 1212416 unused 1024 8192 # (Cyl. 1496*- 1603*)

Working in PROM I cannot boot DIGITAL UNIX from CD using commands like:

>> boot dka100
>> boot -fl 0,80 dka100
>> boot rz1
>> boot rz1a
>> boot rz1c

I get followng messages, the last one after about 10 minutes:

AUDIT_BOOT_STARTS ...
AUDIT_CHECKSUM_GOOD
AUDIT_LOAD_BEGINS
AUDIT_LOAD_DONE
can't open osf_boot

Any suggestions?
