Frequently Asked Questions
Options with onboard configuration memory may need to be configured
in a x86 system until device suppliers provide AXPpci 33 compliant
configuration routines.
• What happens during system startup?
During system startup:
1
The system loads an initial bootstrap from SROM, which transfers
control to the flash ROM.
2
The flash ROM contains the ARC console for Windows NT.
3 If a supported adapter is present, the console(s) attempts to use a
graphics adapter.
If no recognizable adapter is found, the console routes I/O to the
COM1 port at 9600 baud, 8 bits, with no stop bit.
A Digital H8571J adapter allows connection via DECconnect cable.
See Appendix E for a list of console commands.
• If the system does not boot, what should be checked?
If the system does not boot, try the following:
— Check all cables, including a check for:
+ Proper termination of the SCSI cable.
+ Proper cabling of the CD–ROM drives.
+ Proper cabling of the floppy disk cable. There are two ways to
key a floppy cable; both are used. You may have to ignore the
keying when you insert the cable.
— Check for the supported boot device.
— Check that all socketed components are seated.
— Check for the supported graphics adapter, if used.
— Check for console output on the COM1 port.
— Use the system console to check that all installed devices are
accessible:
1
From the ARC console Boot menu, select the Supplementary
menu option.
2
From the Supplementary menu, select the Display hardware
configuration menu option.
