:No.
:The first partition is the EFI GPT (0xee):
:
:% fdisk -1
:******* Working on device /dev/ad0 *******
:...
:parameters to be used for BIOS calculations are:
:cylinders=116280 heads=16 sectors/track=63 (1008 blks/cyl)
:
:Media sector size is 512
:Warning: BIOS sector numbering starts with sector 1
:Information from DOS bootblock is:
:The data for partition 1 is:
:sysid 238 (0xee),(EFI GPT)
: start 40, size 409600 (200 Meg), flag 0
: beg: cyl 0/ head 0/ sector 41;
: end: cyl 406/ head 6/ sector 14
I think I have it mostly figured out, but the 'start 40' in your
output can't be right. The intel documentation says that the
starting LBA in a PMBR record must be set to 1 by definition
(table 11-7 in the 1.10 documentation).
