Subject: Need an entry for /etc/disktab (= shoelace) for 3.5 HD floppy
Date: 21 May 1992 22:30:44 GMT

Hi,

I'm trying to make a floppy from which I can boot a stand-alone
Linux system, ie. I want to boot from the floppy and have my root
filesystem also on it. So I try to use shoelace, but I need a
entry (for /etc/disktab) for an high-density 3.5". I copied the
entry for the 720kb 3.5" and modified it slightly. I'm not sure
what the line with 'fp=' means tho.

This is the entry I currently have.
#|
#| 3.5 inch double sided high density 1440kb disks
#| duplicated from 3.5dsdd
f4|3.5dshd|3.5 inch double sided high density 1440kb disks:\
        :nt#2:se#512:ns#18:md#240:\
        :fp=0xdf 0x2 0x25 0x2 0x12 0x2a 0xff 0x50 0xf6 0x1 0x8:

These are some of the lines of the other entries.
5.25dsdd :fp=0xdf 0x2 0x25 0x2 0x9 0x2a 0xff 0x50 0xf6 0x1 0x8:
5.25dsqd :fp=0xdf 0x2 0x25 0x2 0x9 0x2a 0xff 0x50 0xf6 0x1 0x8:
5.25dshd :fp=0xdf 0x2 0x25 0x2 0xf 0x1b 0xff 0x54 0xf6 0x1 0x8:
3.5dsdd :fp=0xdf 0x2 0x25 0x2 0x9 0x2a 0xff 0x50 0xf6 0x1 0x8:
                                ^ ^ ^
                                | | |
a) number of sectors/track? ----| | |
b) ? --------| |
c) ? ------------------|

I assume a) means the number of sectors/track.
What do b) and c) mean? And what values should I have for a 3.5"?

Thanks for any info.
