eeprom command on Sparcs

[David L. Markowitz]

In comp.sys.sun you write:

>Does /usr/bin/eeprom work on other peoples Sparc's?

Yes.

>On a 4/65 with OS 4.1, (eeprom rev 1.3) mine says
>    eeprom: /dev/eeprom: Error 0

Never seen this.  Is this info accurate?  (Especially the major/minor
device number.)

	# ls -l /dev/eeprom
	crw-r--r--  1 root     staff      3,  11 Jan 10 13:20 /dev/eeprom

>On a 4/490 server, it says,
>    eeprom: software area checksum wrong

RTFM!  Try eeprom -i (which ignores the checksum), or even better eeprom
-i -c (which fixes it).

Don't know about this, but if you are dealing with openprom machines, try
(from the PROM monitor in new mode):

	ok printenv

Where did you get this idea?

[[Ed's Note: This is true for Sparcstations - other architectures will return
the "No such device" error (even those which have the /dev/openprom device
[looked at a 4.1 Sun 3/60]. Check your eeprom man page for more info. -bdg]]
