Hi,
I've just made a grub boot floppy that is, so far, doing a much nicer job of booting multiple Linux distros (and multiple kernels for each) all from my one hard drive than I could every coerce Lilo to do. I'm having only one problem. I'm occasionally getting the following error when trying to boot the distribution/kernel that is on /dev/hda16: 18 : Selected cylinder exceeds maximum supported by BIOS >From the Grub manual; This error is returned when a read is attempted at a linear block address beyond the end of the BIOS translated area. This generally happens if your disk is larger than the BIOS can handle (512MB for (E)IDE disks on older machines or larger than 8GB in general). Now, my /dev/hda16 starts at cylinder 1379 (where the drive has 255 heads, 63 sectors, 1653 cylinders), so this is well over the 8.4GB mark. My BIOS is as up-to-date as available and supports LBA. I've tried this with both the official GNU Grub 0.90 release as well as today's tip of the CVS tree. My exact commands (for the different kernels on this partition) were: root (hd0,15) kernel /vmlinuz root=/dev/hda16 boot AND root (hd0,15) kernel /vmlinuz.old root=/dev/hda16 initrd /initrd.img boot I wouldn't be at all particularly suprised from the above error explanation if my boot attempt for this partition didn't work at all. However, the really confusing or disturbing thing is that it sometimes work perfectly fine and completely boots from this partition, yet sometimes doesn't work and fails with the above message. And, worse, try as I might I can't find any type of reproducibility in it (the only clue seems to be that I can seem to coerce grub to better recognize this partition if I give it a 'geometry (hd0)' on the command line beforehand). Also, it's never worked from this partition when automated from a menu, but can be made to work by entering the exact same commands from the grub command line. Seems strange to me... Also, when it works with this partition, I've had it work both with plain a kernel (2.2.20) and a kernel and initrd together (2.4.16), as above. I searched the grub mail archive, and while I could find information on LBA issues in general, I never found something like this. Sorry if it's been addressed before and I missed it. Thanks for any advice and Happy New Year, everyone! Take care, Daniel PS Kindly cc: me on replies. -- Daniel A.
