[comp.os.minix] booting from 3 1/2 diskette

louboutn@ccvax.ucd.ie (Sylvain Louboutin, Dept. of Computer Science) (03/16/91)

I am running Minix 1.3 on a XT clone equipped with  5 1/4 inch diskette drive
without any problem.  

I would now like to run it on a Mitac MPC 2000V/VE (AT clone with a 286 cpu) and
equipped with a single 3 1/2 inch diskette drive.  I would like to boot from the
diskette and do not want to use the hard disk (I would otherwise have some 
serious diplomatic problems with the colleague who kindly loaned it to me :-) ) 

	( the idea is that I am actually borrowing two Mitac PCs both equipped 
	with ethernet cards and that I would later like to be able to do some 
	experiment with the Amoeba networking utilities,  and test on a real 
	network some stuff that I developped on my XT (under Minix compiled 
	with AM_KERNEL & NONET options.)  But as a first step I would like to 
	be able to boot and run it using the distribution version of Minix i.e.
	compiled without the Amoeba goodies. )

I managed to find another machine having both a 5 1/4 and a 3 1/2 inch diskette
drives and was able to duplicate on 3 1/2 inch diskettes the boot,  the root 
file system and the /usr diskettes from the distribution package.  The 3 1/2 
inches diskettes have been formatted with 720k (80 sectors/tracks;  
9 cylinders;  512 bytes/sectors.) 

I can boot the Mitac from the 3 1/2 inch diskette I made that way.  I can also
check the two other diskettes as being apparently flawless using the standalone
fsck (option 'f' check file system of the main menu.)  So everything looks just
fine so far *except* that when I press the '=' keystroke the system hangs and do
not even start loading the ram disk. 

What did I do wrong?  What should I do?  I would greatly appreciate any input,  
many thanks in advance,
