Specs: Windows XP, p4 3 gigs
I want to boot form a USB pen stick on a PC whose bios does not support usb booting so i thought i could load the usb driver into memory from a CD and then proceed to boot from the USB stick. I suppose this would mean manually starting the USB stick after the USB driver was loaded?

The USB stick is configured to boot from syslinux so i doubt i could manually run the USB - like say i was at a DOS screen or whatever, i don't now how i would start the syslinux boot loader from there.

So basically how can i boot from a usb stick with a bios that doesn't support it?

You can't.

BIOS is firmware, it doesn't belong to the realm of software and you can't manipulate the boot process by loading anything into core memory as RAM is scratched when booting begins. So there is no way at all.

Ok fair enough, you seem to konw what your talking about.

How about if the bios does support booting from a usb stick, how do i know if i am running at USB 1.1 or 2.0 speeds, i read that linux kernels always detect and will load whatever driver but it seems very slow to me.

You may assume you are operating a USB 2.0 as USB 1.1 is so old that just legacy systems or devices are compliant with that architecture.

Anyway that is reported in System's Property under My Computer/Hardware/Peripherals.
