[comp.os.minix] 1.5 Root Device, /dev and 1.44 Meg floppies

Hmm, I'll have to check out this new compression program.  Better than
LHarc?  Huh.  :-)

Anyway, I've finally mostly finished the 1.3->1.5.10 upgrade, but I can't
find any things that have anything to do with a new root file system,
specifically /dev.  I have a 1.44M floppy but I can't access anything past
the 1200K limit, even though I do ``mkfs -t /dev/at1 1440'', and df tells
me there are 1440 blocks.  I presume this is fixed in 1.5, but how do I
rebuild /dev/at*?

It's not exactly fixed.  One way is to create a new root.proto file with the
new blocksize for the 1.44 Meg device.  A better way is to use the makeflops
shell script that comes with Bruce Evans format program.  This creates a whole
set of floppy devices with different minor device numbers depending upon the
drive type.  The correct ones are then linked to your usual floppy device, ie
/dev/fd0.
