I have successfully mounted my old 1.3 hard disk file systems under 1.5.0 using the following technique :- * under 1.3, patch and compile the new fdisk with the new libc.a * boot 1.5.0. You may need to "stty -nl echo^j" (yes, control-j is a newline). * run fdisk on /dev/hd0. Note: if your hard disk does not have 4heads/17sectors, then invoke fdisk as "fdisk -hXX -sYY /dev/hd0" where XX is number of heads and YY is number of sectors per track. * 'h' gives help. In order to mount a 1.3 file system under 1.5.0, you need to change the partition type to be MNX-OLD. Use the 't' command to list the available types. MNX-OLD is 0x80, MINIX is 0x81. * Use the 'n' command to set a 1.3 partition to MNX-OLD. The type value should be 128 (i.e. 0x80). * Reboot 1.5.0 and you should be able to mount an old 1.3 file system!! Mark Goodwin Programmer @ Monash Uni. Comp. Sci.
