HP 330 Service Information Manual page 164

Media formats from which an OS may be booted using the Boot RO Mare:
• LIF (800016)
• SRM
• SDF HP 9000 Model 520; 070016 (Mid-Range Format) (Boot Area)
• UNIX (300016) (Boot Area) (Note that this is different from HP-UX.)
The Boot ROM can boot OSses from the following boot devices:
• SRM via HP 98629 card, /SYSTEMS directory only
• AMIGO protocol HP-IB Discs (e.g. 8290XM, 9895, L-Codes and 7906/20/25)
• HP 98255 EPROM Card in "Disc" format.
• HP 98259 Bubble Memory Card
• CS/80 protocol HP-IB discs (e.g. HP 7908)
• SS /80 protocol HP-IB discs (e.g. HP 9122)
• CS/80 Tape
NOTE
Some of these devices, namely the HP 7906/20/25, may not meet EMI
requirernents when used with Series 300 computers, but their support
in the drivers comes inexpensively with other discs that are supported.
For all devices there are seven generic error messages that can be displayed:
Message
No Device
No Medium
Not Ready
Read Error
Bad Hardware
Bad State
Bus Error
Meaning
Communication was lost with the device.
There was no media (e.g. floppy disc) present.
The device was not ready.
An error occurred while reading from the device.
A hardware fault occurred.
The device is in an unknown or unexpected error state.
A bus error occurred during a memory transfer
If the error terminates the actual load of an OS, it will appear in the next to the bottom line
of the display followed by the device mass storage specifier (e.g. :
HP7908. 803. 0).
If the error
occurs during scanning for OSses, it will not terminate the scan. In this case the error( s) will be
listed on the left hand side of the display. Figure 4-7 is an example display with several errors.
