Description of problem:
After installing Roswell on a Dell Inspiron 7000 (BIOS A15) I noticed when
booting into Windows 2000 SP2 that the APM functionality no longer appeared
under Win2K; specifically battery monitoring (on AC power/battery, battery
life) and suspend to memory or disk.
Removing grub and replacing with System Commander restored the APM
functionality to Win2K. Microsoft's apmstat program indicated a corrupted
APM BIOS when booting under Grub; after removing Grub the utility indicated
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Boot an Inspiron 7000 (BIOS A15) under Grub.
Actual Results: APM unusable.
Expected Results: APM should not be affected by booting Win2K from Grub.
Dell Inspiron 7000, Pentium II 366, A15 BIOS. Linux APM functions
correctly when booting under Grub. Filed as high since a laptop which will
not suspend is a very _hot_ laptop after some time in a case; could result
in system damage.

I'll see what I can do about tracking this one down -- for clarification, you
are putting GRUB in the MBR, correct?
Correct, GRUB was in the MBR.
Can you try the updated grub package at
http://people.redhat.com/~katzj/RPMS/grub-0.90-12.i386.rpm and see if it fixes
(Note that you will need to install the package and then run `/sbin/grub-install
/dev/foo` to get the updated images installed into the MBR)

Works like a charm. Ship it. :-)
It also fixed my complete inability to boot my NT from grub.
/sbin/grub-install, however, broke everything. I added a few sleep's in it as suggested in grub-bug, though it seems the definitive solution to the problem those sleeps
fixes is unclear...
I've added some syncs to grub-0.90-13 (which will be building and going to the
same place in a few minutes probably) using Erich's patch off of the GRUB
mailing list until a better way of making sure the data is flushed to the disk

Any reason the updated RPM hasn't made it to RHN? Seems like it's been a
