Windows protection err when L1 Cache is enabled

[FrankC]

Windows Protection error when internal (L1)cache is
enabled. no error when L1 cache is disabled, but
computer is slow. everything is so slow!!! I think it is
either the motherboard or the AMD internal cache.
Can you tell which?

To start windows takes in excess of 5 minutes.
opening a program takes one to two minutes
scrolling seems to be halting. The Motherboard is
HOT-591P-AT with MVP3 chip set. Award BIOS
the Computer is a year old and has not given any
trouble in the past.

The first error I can remember it giving was a
NTKRNL error message.
the original problem occurred when I tried to install
the Palm III xc desktop and cradle to the serial port
on the motherboard.. After I used it once the port
failed to work, worse yet the other serial port, the
one the mouse was using failed also. I tried to restart
windows but got a NTKRNL error message. I finally
booted in safe mode and discovered no conflicts,
no inactive devices. After much checking on the
windows system I found nothing reported as being
wrong. I removed all unnecessary boards
(modem, network, SCSI card) the mouse, and yes the
palm III cradle, even the printer. Nothing changed.

Thinking this was a software problem, I transferred
all my hard drive info to my son's computer,
formatted my hard drive and reinstalled windows.
The installation took 6+ hours! I knew something
was wrong. After the install the mouse still did not
work on the serial port. I could start in safe mode and
use the keyboard.
I purchased an ISA serial board with two ports,
configured and installed it. Now the
mouse works, the Palm III cradle works. But I have
to change the BIOS to disabled internal L1 cache.
If the internal cache is active (enabled) the computer
gives the "windows protection error."
When I boot up with default BIOS the computer fails
to load windows, it displays "Windows Protection
error" A simple defrag takes forever to check the
disk for errors, with no indication that anything is
happening, then the defrag begins. The display
doesn’t automatically advance in the advanced
information mode.

I noticed a difference between the original system
info and the current info is in the IRQ settings: the
hard drive controller is not listed as Ultra DMA
anymore but windows 98 won't load any other driver.

Could be that you are in "MS-Dos compatability" mode. Check this by going to My computer <right mouse click> -> Properties -> Performance and it should say "configured for optimal performance" or "X drive is using MS-Dos Compatability mode drivers". If this is the case then you should boot up into 'safe-mode' and look under system properties for any devices (sound card, modem, video card, and hard drive controller) that are duplicated. If there are any duplicates delete them and then reboot. Windows will detect and install the device on boot-up (PCI and APCI holders usually have more than one instance). Do each set of duplicates one at a time, rebooting between each set.

Frank did you figure your problem out yet? It seems we have the same problem, It might be your processor doesnt support L1 cache, at least that the conclusion I came up with on mine, how about your L2 cache, is that enabled. Mine runs faster now than it did but I am still having overall performance problems. If you came up with a solution I would love to hear about it.
