netboot for DEBIAN
----------------------
An introduction can be found in README. INSTALL describes the
procedure to create boot floppy or bootrom for the diskless computer.
Here are the most important steps towards a successfull booting
diskless computer:
1) Create a netbootable image of the target operating system - for
linux you can do:
Copy the Linux kernel (configured and compiled for diskless computer)
into the current directory and run mknbi-linux:
mknbi-linux -d rom -i rom -k zImage -o bootImage
This supposes that your kernel image is called zImage, and gives you a
netbootable image named bootImage.
2) For building up the nessary server have a lock at the nfsroot
package and configure /etc/bootptab to point to the boot image.
3) Setup of the client including building the bootrom:
- execute makerom to get two new files in the current directory:
image.flo - this file can be written onto a floppy using dd
(dd if=image.flo of=/dev/fd0)
image.rom - image to be burned into an EPROM
The directory /usr/lib/netboot contains ./binaries and ./utils from
the original distribution. They contain the precompiled images
etc. for the ROM. There are also standard packet driver derived from
Crynwr in /usr/lib/netboot/netdrvr, see /usr/doc/netboot/netdrvr/ for
more information including copyright.
mknbi-dos is the same program as mknbi-linux but for MS-DOS boot disk
image.
