- I am trying to install a/ux on a Fuji 2624, but I am getting some funny
- results. I am using only the outer zone where there is 77 sector/track.
- I have partitioned the disk so that partitions starts on a cylinder
- boundary and with root I made the number of cyl. a multiple of 16 so the
- cyl. blocks should be complete.
-
- However, I get warnings from mkfs (had to invoke directly for root,
- because the startup newfs bombed with error=1) and the output from fsdb
- shows that the cyl. are not being filled.
-
- I also wonder why nsect is 77ms. Isn't this the number of sectors/trk?
-
- I made two partitions because there is a spot that caused 40 defects,
- one on each cyl, that I thought would be best to cover with the swap
- partition, since this does not use ufs which tries to keep account of
- track boundaries.
