It would make no point in overriding BIOS size since by default grub uses BIOS and though sectors past BIOS limit are inaccessible.
However you can make grub bypass the BIOS for disk access with:
grub-install --disk-module=ata

I have found some photos of those situations, on some of them there is:
"error: out of disk
Press any key to continue..."

on grub console I have seen following output:
"
sh:grub> ls
(hd0) (hd0,5) (hd0,3) (hd0,2) (hd0,1)
error: out of disk
";

on other there is:
"error: no such device: <sda5 UUID>"
but UUID of sda5 was correct;

I have noticed that GRUB 2 have problem with my hard drive. Linux has remaped for its purposes the disk parameters:
Size: 320072933376 bytes, 320.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 38913

My laptop BIOS does not fully support this drive it detects only half of it. There is no BIOS update available, but Windows and Linux handle this issue.
But there is problem with GRUB 2.

Sutructure on disk is divided like this (in sectors):
Kod:

   Device              Start         End      Blocks          Id     System
/dev/sda1              1           2611     20972826     83     (not used)
/dev/sda2            2612        7833     41945715     83   Linux jfs
/dev/sda3            7834       15666    62918572+   83   Linux jfs
/dev/sda4           15667       38911   186715462+   f    W95 Ext'd (LBA)
/dev/sda5           15667       38650   184618948+  83  Linux jfs
/dev/sda6           38651       38911    2096451       82  Linux swap / Solaris


GRUB2 has problem when I ask it to load system from sda5, there is no problem with sda2 and sda3. Writing something about table scope has been exceeded, or sometimes UUID not found. Now, I have moved system to sda2, so I no more see this issue but there was nothing to do when I had tried sda5.

Probably GRUB uses BIOS information. Why it cannot remap disk like Linux do this? Or is it other problem?
