| Try it with the L2 cache disabled, or try finding a 256k module.

| The Matrox bios is old. Matrox is up in the 2.x range, currently.

| Re: .1
I did two things, tried again and it worked. First, during the install
I told it to use standard VGA instead of autodetect. Then in setup I
disabled external cache. Now knowing the BIOS for the Matrox is very old,
I am not sure which one fixed the problem but one of them did.
Thanks

| Just install the newest Matrox driver, make sure that works ok, then
re-enable the external cache. That should narrow it down for you...

| 5704.5 | write back or write through? | PTOVAX::PEARLMAN | | Sun Mar 09 1997 16:36 | 5 |
| I seemed to have narrowed this problem down to a defective external
cache but while doing this another question arose. When I turn back on
the external cache I can choose between write back or write through. I
would typically choose write back for performance but is there a
recommended choice or is really my choice?

| Your system was upgraded from a 90 or 100 to 166, right?
I don't think the burst module should have been sold at 166.

| Huh? Please run that by me again....
Last I looked, there's no difference in the bus speed outside the CPU
for 100, 133, and 166 Mhz. How is the burst cache affected by this?
We have a Celebris in the same condition - but it seemd that the 70 ns
memory shipped with it (100 Mhz at that point) could not cut it.
60 ns memory fixed it.
Now how it worked at 100 Mhz with 70 ns memory is another issue -
again, the external bus speed is the same.
There's obviously something else a little odd in these machines - some
enlightenment on exactly what it is would help a lot, as we're using
these machines to test other HW and SW packages.
Thanks,
Chris

| You should probably get a regular cache option for testing
purposes.

| 5704.9 | speed mismatches? | PTOVAX::PEARLMAN | | Mon Mar 10 1997 13:34 | 10 |
| My options are
cache disabled
cache enabled, write through
cache enabled, write back
Where is there an option for burst mode? What is burst mode?
So it sounds like the memory speed might be "too different" from the
cache speed. Is this what the previous replies are saying?
