Description Dave Goldblatt 2001-10-05 02:58:39 UTC

User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.4+)

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.

Comment 2 Jeremy Katz 2001-10-21 23:54:22 UTC

I'll see what I can do about tracking this one down -- for clarification, you
are putting GRUB in the MBR, correct?

Comment 3 Dave Goldblatt 2001-10-22 00:54:24 UTC

Correct, GRUB was in the MBR.

Comment 4 Jeremy Katz 2001-10-27 02:32:35 UTC

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?

Comment 5 Jeremy Katz 2001-10-27 02:33:53 UTC

(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. :-)

Comment 9 Julio Sanchez Fernandez 2001-10-30 10:50:40 UTC

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...

Comment 10 Jeremy Katz 2001-10-31 22:33:36 UTC

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.

Comment 12 Jonathan Larmour 2002-02-06 01:25:52 UTC

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