[PATCH v2 0/2] disk: use maximum number of sectors for LBA

[ValdikSS]

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.

ValdikSS (2):
  disk: read up to 63 sectors in LBA mode
  disk: increase sector size up to 127 for LBA reads
