From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 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 compatibility. Version-Release number of selected component (if applicable): kernel-2.6.0-0.test1.1.26 How reproducible: Always 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. Work-around: <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.

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
Thanks! http://support.ap.dell.com/ap/en/filelib/download/index.asp? fileid=R68080&sid=&os=Windows_NT&searchtype=age Allows download of BIOS upgrades for the Dimension 4600. For me, the problem was corrected (circumvented?) by upgrading the BIOS. --Fred
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 persists. 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/
