Every dog has his day... and tax refund time isn't far off....
Marco is also a hot-blooded Italian. We don't like to be second
best, do we? :^)

| Ed, you are far ahead in contributing to this conference !
It is not so bad to be second when the first one is so good !
( Unfortunately my contribution to this conference is a lot
less then that I'd like it to be and being second is just a dream)

| Marco, perhaps you can give a definite answer to a question on the A2620.
If you are booted off the 68000, can you access the memory on the A2620?
I got one answer from a dealer, and another one from this conference.
And the real answer is...?

2038.5 | Simple question, Sad answer ! | CESARE::ZABOT | Marco Zabot-Adv.Tech.mgr-Turin ACT | Thu Dec 29 1988 04:18 | 3 |
| The answer is : NO, if you boot from the 68000 the 2MB /32 bits
are NOT available !
|
2038.6 | How about the other way ??? | WR1FOR::HARVEYRE | | Thu Dec 29 1988 15:36 | 6 |
| How does the A2620 see memory from its end? Like I have a B2000
with 3 meg total (1 meg on board + 2 meg addon) will the 68020 see
this memory and use it? Or should I try to sell my 2 meg addon when
I upgrade to the A2620?

CSA has advertised a product called 'DRAGSTRIP' which magically
uses two 16-bit memory boards to produce 32-bit memory for use with
their accelerator. Or so I gather. Their ads are none too specific.
Just some random information.

> How does the A2620 see memory from its end?
The A2620 sees all memory when it is running. The reason the
68000 can not see the 32 bit memory on the A2620 has to do with the
way the 68020 is halted which forces the bus on the A2620 into
tristate. This bus is used to access the memory, thus, when it is not
usable neither is the memory.

2038.9 | a way out? | CIMNET::KYZIVAT | Paul Kyzivat | Thu Dec 29 1988 17:37 | 6 |
| Re .8:
Does that mean that "something" could be booted into the 68020 which would
free up the bus so that the 68000 can access that memory?

2038.11 | 2500 without the 2620 | NOBHIL::BODINE_CH | | Tue Oct 30 1990 19:00 | 11 |
| A question for all of the A2500 owners out there.
I tried to take the accelerator board out of an A2500 and put it in an A2000.
When I did, the 2500 would no longer boot. Is there something special that I
would have to do to get the 2500 to boot without the 2620 card?
I would really appreciate some help on this.
Thanks,
Chris

| RE: .11
Try "resetting" with both mouse buttons down. it should bring up a
screen which gives you the opportunity to boot in either
68000
68020
UNIX
of course, you lose the FAST ram if you boot as 68000.
Cheers,
Glenn

| re .12
What I meant to say was......
Reset, THEN depress both mouse buttons. You have a second or two.
My first suggestion might just be physically impossible...

| re: .13
It's not physically impossible, just requires that you hold the mouse
between your teeth.

| RE: .11-.15
Ah ahem, um... gee it seems to me the mouse trick is only possible with the
A26x0 board installed. As I recall .11 he said he could not boot WITHOUT the
board installed. Without the board installed holding down both mouse buttons
has no effect.
I do not know why you should experience trouble booting without the acclerator.
My setup (which is exceptional by almost any measure) has too many disk buffer
and such to fit in a 1 meg RAM system - what I get without the A2630. I can
not boot the 68000 with the card installed either. Unless you have something
like 16+ disks (partitions) with lots of buffers I think this is unlikely.

I believe you're right, the mouse button trick only works if you have the
A26x0. After reading some of the other notes, it appears that there is a
jumper that you can set to tell it to boot from the 68000 by default.
Anybody know what it is?
