Multiple items on boot line

[doglover]

Hello. I need to use fb1024x768 at the boot prompt, but I also want to have acpi=off. I have tried to combine them at the boot: prompt without success. How does one do this?

Thanks.

separate them by a space

Yes. thanks, but it was the syntax that I was trying to glean.

Anyhow, I did finally figure it out after experimenting some more. For those who will follow ...

You have to start with the fb1024 x 768.
After that, it doesn't matter whether you have the knoppix word in there or not.
You can use

fb1024x768 knoppix acpi=off noapm

or you can have

fb1024x768 acpi=off noapm

Both work.

Knoppix acpi=off fb1024x768

does not work.

Happy Holidays,
IMF

for the dumbies (me included )
what's the fb trying to do ?
and ideas on why it should work before the knoppix command but not after ?

Easy enough,

fb1024x768 is a label, not an option. So it will just be ignored on the cli.

The getops() will sequence through the cli option strings looking for a specific option. So if there is a string there that doesn't have a handler, then it will just be bypassed.

If an option is a viable option and it isn't working, or seems to be ignored ... it is likely that its' handeler is inadvertainly missing in the file that is used to pass those options.



.../boot/isolinux/isolinux.cfg

LABEL fb1024x768
KERNEL linux
APPEND ramdisk_size=100000 init=/etc/init lang=us apm=power-off vga=791 xmodule=fbdev initrd=minirt.gz nomce quiet BOOT_IMAGE=knoppix


The 'fb' adds graphic capabilities to the console. Allows different resolutions and some other graphic facilities. Such as the tux logo that can be had during boot if set in the kernel
