To bypass the  maximum disk size limitation of some BIOS's grub can use the
ata module by means of the command:

grub-install --disk-module=ata

However, this disk-module option is not preserved during an upgrade of grub-pc

Similarly other modules may be needed to be included as options to the
grub-install command and are not included when grub-pc is updated.

Could these options somehow be preserved for when grub-pc gets upgraded so
that grub-install is run with the same modules and disk-modules options?
