Write back causes weird behavior. 4x won't run. (Ed.
Finally corrected!)
Unable to install Win98 because the processor is not
at least
66MHz. NT4.0 fails on install also (unable to
find files needed
for networking).
Jim Shorney
Use "setup /nm" for W98. You may have SCSI
problems w/98. I was
never able to get it to run w/o DOS mode using the
Evergreen. Put the stock
50Mhz back in and it was fine, so I am currently running
NT4.0 SP 5
on mine. No problems with NT.
>I got it to run just fine with the Type 3 DX50.
Never understood why
others had so many problems with it.
From Peter
That Type 3 DX50 (-xMx models) is the only
exception I found
so far. All my other machines (Mod. 90 / T2 DX2-25/50,
8595-AKD /T1 DX-33,
9577-1NA / DX2-33/66) fell flat on the face and into
16-bit mode. Only
the "Lacuna" with the Fast SCSI-2 Future-Domain derived
controller and
the 9595-AMT with T3 DX50 worked.
> Is this upgrade possible with the Kingston Turbo
Chip but not the
Evergreen?
Jim Shorney
Known to work better with the Evergreen. Cache
policy problems
with the Kingston. Can't see more than 32 MB,
floppy no workie etc...
Same problems with write back cache on the
Evergreen. Evergreen has
the jumper which fixes those.
Ed- I have a TC133-
I'll be verifying
this on a complex with different FRUs.

> Hi Jim,
> What processor did you use to upgrade
the type 3 complex? It's running at 150mhz? And which
processor did you remove to upgrade it? The 486DX-50?
Thanks.
> Terrance
Hi Terrance,
Well, this is another one of those subjects that has
been discussed
to death here, but here's the scoop: I replaced
the 486DX-50 with
an AMD 5x86-P75ADW (some folks say you need the ADZ
because of the higher
thermal rating, but I had no troubles withe the ADW).
I used a
PowerLeap interposer to get the voltage right, with a
standard fan/heatsink,
and set the CPU to x3 mode to get 150 MHz. It
happily ran OS/2 Warp
4.0 and NT Workstation 4.0 for many months (until last
night when I installed
the type 4), and was rock stable. Not bad for a
cheap,
screwy CPU... :)
