Announcing a patch series for isohybrid.c
Hi,
following will be 6 patch proposals for isohybrid.c
1: Encode GPT partition names as UTF-16LE
2: Correct blocking factor in APM partition block counts
3: Correct end block address of first GPT partition
4: Write GPT backup to the very end of the image
5: Change all fseek(3) to fseeko(3)
6: Introduce option --mbr and make isohybrid.c compilable standalone
If the form needs adjustments,

isohybrid.c, problem reports and questions
...itialise_apm() i see two occasions where block counts are handled:
- This should probably be 4 rather than 0x10:
part->block_count = bendian_int(0x10);
- These _count variables should probably be divided by 4 before being
submitted to bendian_int():
part->block_count = bendian_int(efi_count);
part->data_count = bendian_int(efi_count);
part->block_count = bendian_int(mac_count);
part->data_count = bendian_int(mac_count);
The numbers stem from read_efi_catalogue() which deals with EFI blocks
of 512 bytes.
