Hi Folks,
I'm trying to automate a sequence of BTX commands and I'm hitting some
snags. I've got some minor forth experience, but it isn't enough.
My machine uses the standard bootloader and doesn't present a menu for
the user. By default, the machine boots a standard kernel and fs-image
file and everything is happy. Sometimes, though, I want my users to be
able to boot an alternate kernel and fs-image. To do this, what they do
now is:
- wait for the default kernel to start loading
- hit the space bar
- BTX breaks out and gives them a prompt
- they type four commands:
- unload
- load /kernel
- load -t md_image /altfs-image
- boot
I'd like to replace those four commands with one command to make things
nicer for them.
So I tried to define the obvious forth word:
: altboot unload load /kernel load -t md_image /altfs-image boot ;
which fails to compile because /kernel isn't a word.
These all compile, but reboot when invoked
: altboot unload s" /kernel" load ; \ reboots the box
: altboot unload load s" /kernel" ; \ reboots the box
: altboot unload ." /kernel" load ; \ reboots the box
: altboot unload load ." /kernel" ; \ reboots the box
I'm stumped. Any suggestions?
Kelly
