I'm using a Dell Precision 690 workstation. I finally managed to install grub on the MBR of my first SCSI hard disk. (It didn't install during the regular fc6 test3 install -- see bug #207008.) Now when I try to boot linux, it gives me an error: Error 28: selected item cannot fit into memory I made a grub boot floppy with knoppix 5.0.1, and that *is* able to boot my system: I used the grub-floppy command in knoppix, then booted from the resulting floppy. Then in grub: configfile (hd1,0)/boot/grub.conf and I select the linux kernel and it boots without error 28.
I have experienced the same issue with the the following hardware configuration. supermicro X7DBE+ Rev 2.01 with 4 GIGS of Ram DDR II Buffered. 200Gig SATA Harddrive using on-board sata controller. Only 1 HD. Using 2 Dual Core Intel Xeon CPUs. I get the same exact issue. Tried going back to FC5 everything works except the NIC cards on the motherboard are not recognized during the installation. However the OS will load and reboot fine.
I tried again with the new grub-0.97-12 and kernel-2.6.18-1.2689.fc6 packages, and grub still fails with the same error message. Grub from knoppix still works. Also, I discovered today that in order to install grub from within linux (using /sbin/grub), I had to add my second hard drive (/dev/sdb as (hd1)) to /boot/grub/device.map manually. Maybe anaconda didn't detect all the hard drives correctly, which might be why grub didn't get installed initially.
