[comp.sys.mac] MAC II ROM Upgrade

lchirica@polyslo.UUCP (Laurian Chirica) (04/16/88)

Quote from Info World, April 11, 1988:

"Mac II users looking for more fire-power might ask their dealers
for the free ROM upgrade required to run A/UX.  I am not saying to
pay the $4,000 or so to actually buy A/UX; just get the ROM upgrade.
It is free, it gets you a brand-new mother board, and makes disk
accesses under Finder twice as fast.  No wonder Apple has been so
quiet about this freebie."

Question:  Does anyone know anything more about this?  My dealer
knows nothing.

The ROM upgrade has not yet shipped to dealers.  Keep asking your dealer
about it, though, as it's NOT likely to be announced to the general
public when it does ship.

From the unofficial rumor-quenching arena -- no, you DON'T have to get
any kind of ROM upgrade, OR any upgrade whatsoever to run A/UX. All you
need is minimum of 2MB memory and a PMMU plugged into the socket. This is
a bizarre rumor -- because I can't think of anything that it could remotely
be based on. I mean, if there is a brand-new motherboard out, we here in
Apple Software Engineering might like to get a few for testing purposes ...
:-) :-) etc. Perhaps there was some kind of a third party announcement
that got garbled???

Well, there _is_ a new ROM for the Mac II--it makes the Slot Manager use 32-bit
mode so you can have more than 1MB of address space on a card.  Maybe you_
__should_ get a few for testing purposes...

I have found out that this upgrade exists and is primarily to
allow the use of NuBus cards with more than 1MB of memory.

The upgrade appears to be a swap of the logic board for a rev
B logic board. Does anyone out there have any details on 
what the differences really are? I have conflicting reports
from the net and different service people here locally
as to what effects this upgrade has.

The MacII logic board upgrade does two (and only two) things:

It fixes a ROM bug so you can can have more than
1MB of address space on a NuBus card.

It changes a HAL that caused a slight timing problem between
NuBus cards that can become bus master.

You would need this upgrade if:

You have a NuBus card that needs more than 1MB of address space
You have NuBus card(s) that can become bus master.

You do NOT need this upgrade if:

You are running A/UX (If you don't believe me, I have two machines
doing it, and I don't know how to tell them the bad news.... :-))
You are using an Apple Video card or Ethertalk interface card 
(neither of them can become bus master).

The only NuBus card I know of (to date) that needs this upgrade 
is the National Semiconductor RAM board.

This board will NOT

Make your disk access twice as fast.

Philip,

I'll buy that you don't need to upgrade in any way to run A/UX, but what if
you want to have more than a meg of ram on a nubus card?  You do need a ROM
upgrade for that and Apple is apperently getting ready to release this.
As for wether this will be free or not is no in my metier.

If you can't diseminate information about an, as yet, unannounced product,
that is fine, but please do not diseminate misinformation or worse yet
disinformation.  While not officially announced, it is a fairly well established
fact that it will happen and MUST happen unless the Mac II is to be closed to
large applications, which, under unix, when running in conjunction with
other tasks, can very easily require more than the what, 14 megs the system
can handle now.

I was under the impression that the 1 meg per slot limit was only under
Mac OS, and that everything worked OK under A/UX. National Semiconductor is
supposedly shipping their boards for use with A/UX, so I assumed it would
work (misrepresentation?) Anybody know if this is true?

Your impression is correct.  It is possible, for example, to shove in Nat.
Semi. boards fully loaded in each of the nuBus slots and get a godawful lot
of memory accessible to the CPU.  Of course, that makes little sense, as a
general rule!

Hello,

A/UX in not affected by the '1-Meg-per-slot' limit; just MacOS.

Hope this helps.

Yes, I've have seen the National Semi boards working. I use one myself.
I have seen 5 boards in one system (88 megabytes of memory) running.

Neat!  So, has anyone tried porting the BSD ramdisk driver to A/UX?
That's one way to sort of get more free space elsewhere, since you could put 
/tmp and multiple swap areas on multiple boards. (maybe 1 swap/board, since
you might be able to fool the swap strategy routines into conserving nubus
bandwith like they would disk interface bandwidth in deciding which disk to
talk to.) At least A/UX isn't crippled like SunOS in terms of addressable 
memory (I hear from 3rd party memory vendors that you can physically address 
64M in a Sun-3/160, but only 24M is supported by the OS.  Quite a shame.)

Swap to ram?  I like the idea of /tmp (and /usr/tmp for that matter) on
a ram disk.  And then the system might benefit from having the pipe device
be a ram disk.  But swap space?  You're decreasing your available memory,
which causes more swapping.  It seems that just keeping that memory available
to programs would eliminate swapping almost entirely.

Besides, is ram really cheaper per megabyte than disk?  It seems really
unlikely now that chip prices are going back up.

There is a RAM disk available now from National I believe. However, you can
also specify a very large amount of buffers for the buffer cache (NBUF=nnnn
using the A/UX kconfig command) and the A/UX kernel will take memory for the
buffer cache from slower NuBus memory boards before it allocates from the
faster SIMM memory banks. I have 16MB of buffer cache myself. Sometimes,
some commands, especially large file copies when moving directories, work
unbelievably fast!

Instead of a RAM disk, how about 80MB of buffer cache??? Sync might slow your
system down a bit though ... :-)

I stand corrected, yes, under unix, the MAc can utilize more than one meg
per card, it is in the native environment that it needs the ROM upgrade to
do it. But, I have laread seen a situation arise where the amount of ram
without the upgrade roms was not enough in the native mode, so the comment
is still valid. You just don't need to upgrade for unix is all.

Experiments with UNIX and a solid-state disk [Sugit Kumar's Ph.D. dissertation,
Case Western Reserve University, late '70's] showed that the best use
of a zero-latency disk with UNIX was for /tmp, /usr/tmp, and commonly-
used system programs.  The reason that there is less gain with using
it for a swap device is that there is only ONE rotational latency, then
the whole swap area is written out to a contiguous disk file.  On the
usual file system files, you can incur a number of rotational latencies
per file.

Of course, I don't know how the AUX driver and hardware really work, nor
what the interleave factor is on the hard disk.  These would affect the
results Sugit obtained, as he was working with a word-addressable
disk.

More details upon demand, if any.
