- I am trying to figure out how to boot from a floppy drive
- in case I experience some catostrophic error.
-
- I was successful in using 'installboot' to get the boot
- block set up correctly on a floppy diskette.
-
- I proceeded to boot from the monitor and received the following
- information:
- > b floppy
- Rebooting with command : floppy
- Boot device : /fd File and args: vmunix
- Bootblock: libprom.a: Romvec Version 2
- Boot: libprom.a: Romvec Version 2
- root on /fd fstype 4.2
- Boot: vmunix
- Boot: lookuppn failed: No such file or directory (errno 2)
- ......... more info ............
-
- I assume the problen is that vmunix is not on the
- floppy. Since the size of the kernel is about 1.7Mb
- it is not possible to copy this to the diskette.
-
- Questions:
- 1). Is it possible to tell the boot program to use the
- kernel on the disk?
-
-
- 2). If I get the kernel down to less than 1.4 Mb is it
- possible to tell the boot program the kernel resides
- on another floppy and then insert a second floppy
- (with the kernel on it) during the boot process?
