Re: [Bug-xorriso] Test Proposal for [bug #46716] Protective MBR partition is not marked as bootable

Hi,

  MBR partition table:   N Status  Type        Start       Blocks
  MBR partition      :   1   0x80  0x83            0        32220
  MBR partition      :   2   0x00  0xef        32220         5760

And the other non-working "EFI Boot" offer is gone ?
(That would mean it was the APM/HFS+ boot path.)

  MBR partition table:   N Status  Type        Start       Blocks
  MBR partition      :   1   0x00  0xee            1        32283
  MBR partition      :   2   0x80  0x00            1        32283

But if it is beneficial, i could support it by some new xorriso
option.

Are there any bootable media for it, which are not from Apple ?

(I.e. two working boot offers ?)

That's why i said "Oh". Not having to patch would remove the need
for random access to the output file.
It works with xorriso-1.3.2.
(But not with 1.2.2 from Debian oldstable, because not knowing
 --grub2-mbr and --grub2-boot-info, and because -append_partition
 was not properly coordinated with --protective-msdos-label.)


Have a nice day :)
