Re: Flavours of rebooting (was 3C509 acting strangely on Win95/Debian ...)

[Bruce Perens]

It belongs on the LILO command line that boots the linux kernel (given
that you boot with LILO). It's interpreted by the _kernel_, not any
user-mode program, at boot time, and it saves that parameter until halt
time. You can also hack the kernel to hard-code the booting method.

Another solution would be an /etc/init.d script that saves the motor
positions when halting, and restores them while booting. Of course,
this is not as nice as having the hardware remember. You might have to
re-calibrate at boot time just to make sure the stored positions are
right.

Thanks

I think this may be the answer to my problem but I don't know how to
apply it.

My boxes that are Intel TC (Tucson) mobo-based flick the power light off
when they reboot from linux to W95. Unfortunately this has the side-effect
of making an ISA motor-drive card reset, and it loses its knowledge of
the motor positions.

I therefore want as warm a reboot as possible. Where do I put reboot=w ?
man reboot/shutdown/inittab etc. have lots of -r style-of-syntax switches
but I can't see anything like reboot=X.

Other background:

>From power-on, the machine boots directly into W95.
For linux, I shutdown W95 to an MSDOS prompt and run loadlin.
To revert to W95, I Ctrl-Alt-Del which does (/etc/inittab)
ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now

Cheers,
