how do you know if your PC can boot from a USB?

Q. I am looking to get a linux LIVE usb. And was wondering if my PC is new enough for it to boot from the USB.

Its a 2002 IBM Netvista desktop.(solid nice machine)

A. Insert a blank USB stick (some BIOS versions won't give the USB boot option if one isn't connected!) and restart.

On startup, keep tapping either F1, F2, F10,(Be Aware that some manufacturers also use F10 for system recovery!) Esc or Del (depending on your system) until you get to the BIOS setup screen.

Look for an option to change boot device, or similar, and see it it's listed. If it is, you're good to go âº

How to turn my usb key into a network key
Q. I would like to boot linux from a live usb but my BIOS dose not support boot from usb. I was worndering if I got a USB to RJ-45 adapter would my usb key show up as a network drive in my BIOS

A. IBM developerWorks has published a detailed technical article on booting Linux from external FireWire or USB drives, in conjunction with a boot floppy, USB storage device, internal drive partition, or another device recognized by the system BIOS. The article also explains basic bootloader concepts that may interest embedded Linux developers.

Is thumb-drive-based Fedora slower than said operating system installed to a hard disk?
Q. I've finally convinced my father to let me install a Linux distribution.
The only catch? It has to be on my USB drive. So, I'm going to install Fedora Live USB.

Will there be any differences in speed compared to hard-drive located Fedora? I don't want to have a bad impression of the operating system.

A. A RAM-based drive (which is a thumb drive) is actually faster than a hard drive, which is why Vista allows you to use one as a disk cache - to speed up disk access.

The difference will be speed - you'll gain it. (But a thumb drive has a limited number of writes, which is why that's only a temporary solution. You'll kill the thumb drive in a year, or a few years. An SD card may be a lot cheaper for the same size - if your computer has a card reader.)
