You don't say whether this problem existed before you attempted to install FC2, or if it happened as a direct result of a failed install attempt. However, this is most likely related to the extremely well publicised issue regarding a known bug that affects all the recent 2.6 based distros. The quick summary is that it is a combination of a bug in parted, running the 2.6 kernel, and failing to explicitly specify LBA mode access on IDE hard drives, in the mobo BIOS settings. AFAIK the specific issue is that the 2.6 kernel IDE disk geometry calculation is now taken directly from a disk query, and not from a BIOS call as with 2.4. If you get the source trees for 2.4 and 2.6 then you can have a good look at the changes in disk geometry handling: diff -Nur \ /usr/src/linux-2.4/drivers/ide/ide-geometry.c \ /mnt/beta/usr/src/linux-2.6.5-1.358/drivers/ide/ide-generic.c Rather than repeat the mass of documentation on the subject, I'll just post a small selection of relevant links: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=115980 http://www.redhat.com/archives/fedora-test-list/2004-May/msg02114.html http://www.redhat.com/archives/fedora-devel-list/2004-May/msg00908.html http://www.ces.clemson.edu/linux/fc2.html http://lists.gnu.org/archive/html/bug-parted/2003-11/msg00051.html http://tinyurl.com/35yyh (Google Groups) This issue is so hot, it even got *Slashdotted*, although the OP incorrectly attributes this problem exclusively to Fedora. http://slashdot.org/articles/04/05/23/1448209.shtml?tid=110&tid=187 - K.
