Hitting cylinder limit with GRUB

[Glenn Becker]

Hi -

About a year ago I replaced the 2.1G hard drive on a Toshiba 470CDT with
a 30g one, updated the BIOS, then got FreeBSD set up 'next to' Slackware
Linux. It's all been working nicely since then.

Now I'm trying to set up a 'triple-boot' on this same machine, adding
Win98 into the middle - yesterday I read a newish HOWTO on how to do
this using GRUB (Linux+Win9x+Grub-HOWTO on TLDP).

I repartitioned using parterd, and then I installed GRUB (0.93) using
the grub-install command, onto /dev/hda.

Linux boots fine now from GRUB, I have the 'menu.lst' file in the right
place, but GRUB seems unable to deal with anything above the 'cylinder
limit' (it's not specifying but I assume the 1024 cylinder limit). I've
been booting things from above there for over a year using LILO. I tried
re-installing GRUB using grub-install --force-lba. Same result.

Here is the partition table on the machine:

Disk /dev/hda: 255 heads, 63 sectors, 3648 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1             1      1216   9767488+  83  Linux
/dev/hda2          1217      1275    473917+  82  Linux swap
/dev/hda3          1276      2097   6602715    c  Win95 FAT32 (LBA)
/dev/hda4   *      2098      3648  12458407+  a5  FreeBSD

I've forgotten why the boot flag is set on the last partition,
incidentally.

Thanks in advance for any advice or pointers: I will keep searching the
bug-grub archives.

Best,

Glenn Becker
