The above renewed emphasis is mine.

I doubt this for the following reasons:
 1. The BIOS boots with grub legacy, and an earlier version of
    GRUB2 as well.
 2. Even the problematic version of GRUB2 goes into rescue mode.
 3. The quoted reports talk about a BIOS that cannot do either of (1)
 or (2) and GRUB getting stuck at an even earlier stage.

It may be a problem of the BIOS incorrectly identifying or being
unable to load the additional (required) portions of stage2.

Regards,

Kapil.
