Comment (by starsseed):
haiku_loader does not work on my laptop (see the bug #4408 #5539 #5696
#5720) so, I can't test on it. Neither on my desktop system whom BIOS
doesn't care about CHS informations...
But I remember having problems to create a valid MBR/partition-table for
my USB key, and I never completely understood why! (now I create the MBR
and the partition from windows and copy the boot-code area from an
AnyBoot-image with dd)
Preroll, did you test the patch ?

Note that:
- FF FF FF implies a disks with UUID partition table (EFI) then EF FF FF
would be better
- since DriveSetup creates the first partition at sector CHS={01 02 00}
(i.e. Cylinder=0/Head=1/sector=2 or LBA=40) it seems it does not take care
about the disk geometry. I think it's not correct : the 1st partition
should be aligned on the 1st sector (2nd,3rd,4th partition should be
aligned on head*sector - 1st sector/Head 0).
