4xagp

I have an ongoing problem with getting my radeon 7000 to
run at 4x. It has persisted since windows 98 se but
occasionally it was possible to get it to run, apparently
by switching pci card locations. However the last time I
reinstalled Se, it would not in that configuration or any
other, so since I had recently aquired XP I installed
that. In xp it has become totally impossible to to get it
to run at 4x. Anytime it is to 4x in the bios and I set
the ati control panel smart gart to 4x, some period of
time after the xp splash screen displays during the boot
process and longer than it should take to display the
desktop it shows a garbled blue screen for an instant and
reboots. The log file I tracked down says it is due to the
driver getting stuck in an infinite loop. I have the
latest drivers for both my via chipset and the radeon and
have tried all other available drivers as well. It will
run at 2x when the gart is set to 2x, the bios 4x is
disabled, or both. Have tried all system ram
configurations available with my existing modules. No
conflicts in device manager.
