Empirical evidence suggests that the F1-4 keys map to the corresponding entries in the partition table of the MBR. [Hope I get the terms reasonably close....] Thus: d144(4.6-S)[7] sudo boot0cfg -v ad0 Password: # flag start chs type end chs offset size 1 0x80 73: 0: 1 0xa5 349:239:63 1103760 4188240 2 0x00 350: 0: 1 0xa5 626:239:63 5292000 4188240 3 0x00 627: 0: 1 0xa5 1023:239:63 9480240 29589840 4 0x00 0: 1: 1 0xa0 72:239:63 63 1103697 version=1.0 drive=0x80 mask=0x7 ticks=182 options=nopacket,update,nosetdrv default_selection=F1 (Slice 1) d144(4.6-S)[8] In the above case, F1 corresponds to the entry labelled "1" (and so on), even though I set things up so that it's the 4th entry that refers to the first slice one would encounter on the disk.
