grub appears to prevent APM working for Win2K

From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.4+) Gecko/20011001 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 no problems. Version-Release number of selected component (if applicable): How reproducible: Always 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. Additional info: 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 the problem?
(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 is determined.

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