When I install SP1 it does it thing and tells me to restart. It then
configurs. It gets to 98 percent, then it shows shutting down. When it
restarts as soon as windows starts to load, I get a black screen saying the
file acpi.sys is missing of corrupt. I can use the windows disk to repair
it. But the update is not installed. I have tried four diffrent times with
the same result. I even deleted the windows update folder. How do I fix
this?

Hi,

First check with the manufacturer for any needed BIOS update prior to
installing SP1. A message about acpi.sys can be an indicator of an issue
with the system BIOS instruction set not being fully compliant with current
standards (they change with time, so even newer machines can have outdated
BIOS').
