Prepared bootman to boot from other than the first drive.
The ioctl B_GET_BIOS_DRIVE_ID still needs to be implemented. Only partitions from the first drive can be added to the boot menu, until B_GET_BIOS_DRIVE_ID is implemented. Fixed bug calculating the offset of the first partition. off_t is a signed type, the fact? that Be FS is a 64-bit filesystem, lead me to the wrong assumption that this is an unsigned type :-( git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25044 a95241bf-73f2-0310-859d-f6bbb57e9c96
