Subject: your next glue routine, when you have time
Date: Fri, 4 Feb 1994 21:02:17 -0500
Hornbake recently had been hit be someone who had reset pram on a
bunch of Macs. Forceether and forceremote are now only 2/7 of
what is needed to reset them for normal operation. The others are:
set 32-bit addressing on (critical), turn ramdisk on and set to
4000K (important), set disk cache to 512K (minor), set map to
Washington (minor until I put Nettime out, not soon), and set
040 cache switch to More Compatible (important until yukky old
MacWriteII goes away, not soon). The control panels are on the
Centris/SI setup disk for manual operation, but the sad fact is
that the wscoords aren't always good about going around and doing
it, and the disk for lab attendants/first-aiders has to be faceless.
I like the a-la-carte approach of forceether and forceremote, since
2 labs still have SIs which don't set the ramdisk or the 040 cache
(and you can leave FE and FR as is). Maybe you could snoop around
and look at where those pram settings live, in your copious spare
time of course. Thanks!

Forgot to add number 8: Appletalk on in the Chooser (critical).
================
1. (ForceEther) Force AppleTalk Network selection to be EtherTalk.
PRAM location E0-E3 to slot and resource and also other data.
2. (ForceRemote) Force Boot Device to be EtherNet network card.
PRAM location 78-7B set to slot and resource via SetDefaultStartup trap.
3. Set 32-bit addressing on
Might be PRAM location 8A. Might be Q610 specific
4. Turn RAM Disk on and set to 4000K
PRAM location AF. Find appropriate value
5. Set disk cache to 512K
6. Set Map to Washington
PRAM locations E4-EF. Format documented in MacTutor.
7. Set 040 cache switch to "More Compatable"
8. Turn on AppleTalk (in the Chooser)
