Subject: bootup command line list

Could anyone let me know where I can find a full list for bootup command
line parameters, such as mem=1G, etc? I'd like to boot a Hyper-threading
enabled kernel using only one processor on a dual-processor system.
Currently my solution is to physically unplug the secondary CPU.

Thanks for any suggestion

Hi:

Thanks for the replies for this thread. Yes, I found useful information
both in the man page and the txt file. Does anyone by chance know how to
disable hyper-threading in 2.6.x kernel? In kernels eariler than 2.4.20,
there was an option called "noht", but it no longer works for latest
kernels? Is it unsupported or changed to other options?

Thanks
