GRUB2 limits number of sectors read at once in LBA mode to the number reported in CHS disk geometry by BIOS. This is unnecessary, as IBM/MS INT13 Extensions does not have such limit and it is safe to read up to 127 sectors in a single call.
This fixes greatly increased boot times on WYSE C10LE x86 thin client with Phoenix bios.
