The following fields and values are for systems with an EEPROM:
hwupdate
A valid date, such as “7/12/95”. The strings “today” and “now” are also acceptable.
memsize
How much memory, in megabytes, is installed in the system.
memtest
How much memory, in megabytes, is to be tested upon power-up.
scrsize
The size of the screen. Acceptable values are “1024x1024”, “1152x900”, “1600x1280”, and “1440x1440”.
watchdog_reboot
If true, the system will reboot upon reset. Otherwise, the system will fall into the monitor.
default_boot
If true, the system will use the boot device stored in bootdev.
bootdev
Specifies the default boot device in the form cc(x,x,x), where ‘cc' is a combination of two letters such as ‘sd' or ‘le' and each ‘x' is a hexadecimal number between 0 and ff, less the prepending ‘0x'.
kbdtype
This value is “0” for all Sun keyboards.
console
Specifies the console type. Valid values are “b&w”, “ttya”, “ttyb”, “color”, and “p4opt”.
keyclick
If true, the keys click annoyingly.
diagdev
This is a string very similar to that used by bootdev. It specifies the default boot device when the diagnostic switch is turned on.
diagpath
A 40-character, NULL-terminated string specifying the kernel or standalone program to load when the diagnostic switch is turned on.
columns
An 8-bit integer specifying the number of columns on the console.
rows
An 8-bit integer specifying the number of rows on the console.
ttya_use_baud
Use the baud rate stored in ttya_baud instead of the default 9600.
ttya_baud
A 16-bit integer specifying the baud rate to use on ttya.
ttya_no_rtsdtr
If true, disables RTS/DTR.
ttyb_use_baud
Similar to ttya_use_baud, but for ttyb.
ttyb_baud
Similar to ttya_baud, but for ttyb.
ttyb_no_rtsdtr
Similar to ttya_no_rtsdtr, but for ttyb.
banner
An 80-character, NULL-terminated string to use at power-up instead of the default Sun banner.
Note that the
secure,
bad_login, and
password fields are not currently supported.
Since the openprom is designed such that the field names are arbitrary, explaining them here is dubious. Below are field names and values that one is likely to see on a system with an openprom. NOTE: this list may be incomplete or incorrect due to differences between revisions of the openprom.
sunmon-compat?
If true, the old EEPROM-style interface will be used while in the monitor, rather than the openprom-style interface.
selftest-#megs
A 32-bit integer specifying the number of megabytes of memory to test upon power-up.
oem-logo
A 64bitx64bit bitmap in Sun Iconedit format. To set the bitmap, give the pathname of the file containing the image. NOTE: this property is not yet supported.
oem-logo?
If true, enables the use of the bitmap stored in oem-logo rather than the default Sun logo.
oem-banner
A string to use at power up, rather than the default Sun banner.
oem-banner?
If true, enables the use of the banner stored in oem-banner rather than the default Sun banner.
ttya-mode
A string of five comma separated fields in the format “9600,8,n,1,-”. The first field is the baud rate. The second field is the number of data bits. The third field is the parity; acceptable values for parity are ‘n' (none), ‘e' (even), ‘o' (odd), ‘m' (mark), and ‘s' (space). The fourth field is the number of stop bits. The fifth field is the ‘handshake' field; acceptable values are ‘-' (none), ‘h' (RTS/CTS), and ‘s' (Xon/Xoff).
ttya-rts-dtr-off
If true, the system will ignore RTS/DTR.
ttya-ignore-cd
If true, the system will ignore carrier detect.
ttyb-mode
Similar to ttya-mode, but for ttyb.
ttyb-rts-dtr-off
Similar to ttya-rts-dtr-off, but for ttyb.
ttyb-ignore-cd
Similar to ttya-ignore-cd, but for ttyb.
sbus-probe-list
Four digits in the format “0123” specifying which order to probe the sbus at power-up. It is unlikely that this value should ever be changed.
screen-#columns
An 8-bit integer specifying the number of columns on the console.
screen-#rows
An 8-bit integer specifying the number of rows on the console.
auto-boot?
If true, the system will boot automatically at power-up.
watchdog-reboot?
If true, the system will reboot upon reset. Otherwise, system will fall into the monitor.
input-device
One of the strings “keyboard”, “ttya”, or “ttyb” specifying the default console input device.
output-device
One of the strings “screen”, “ttya”, or “ttyb” specifying the default console output device.
keyboard-click?
If true, the keys click annoyingly.
sd-targets
A string in the format “31204567” describing the translation of physical to logical target.
st-targets
Similar to sd-targets, but for tapes. The default translation is “45670123”.
scsi-initiator-id
The SCSI ID of the on-board SCSI controller.
hardware-revision
A 7-character string describing a date, such as “25May95”.
last-hardware-update
Similar to hardware-revision, describing when the CPU was last updated.
diag-switch?
If true, the system will boot and run in diagnostic mode.
