Description of problem:
(New) Dell Inspirion 4600 with 512 MB memory. Standard developer install of
RH9.0 with updates. Installed new tools + kernel-2.6.0-test1.1.24. Booted and
ran OK. When rebooting, whether to that kernel or to the other tested
(2.4.20-18), BIOS warns that amount of available memory has change. This is the
result of a switch to "OS install mode" which limite memory to 256 MB. Unsetting
this mode and reboot results in detection of all memory. This does not happen
with 2.4.20-18 and happens with both 2.6.0-test1.1.24 and 2.6.0-test1.1.26.

I assume this is really a kernel vs hardware issue and not specific to the RH
package, but couldn't figure out how to report it to kernel.org.

PS: Thanks for rpms! Failed to compile/install source, but can still test hw

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot 2.6.0 kernel.
2. Reboot (either 2.6.0 again, or 2.4.20-18 - same result)
3. => system now limited to 256 MB in "OS install mode"

Actual Results:  (3) above.

<F2> for BIOS setup.
OS install mode from on -> off.
exit & save
(bios complaints memory size has changed)
F1 to ignore
... normal boot

Expected Results:  Normal boot with 512 MB, as seen with 2.4.20-18.

Comment 1 Bryan O'Sullivan 2004-01-21 12:51:10 EST
This is an upstream bug, not Red Hat specific.  I don't use Arjan's
kernels, and it happens on the Dimension 4600 boxes at my workplace.

See http://bugzilla.kernel.org/show_bug.cgi?id=1927

Allows download of BIOS upgrades for the Dimension 4600. For me, the 
problem was corrected (circumvented?) by upgrading the BIOS.

Comment 3 Bugzilla owner 2004-09-30 11:41:19 EDT
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
