First an explination

I go to school where they use at least 3 diferent computers currently to use them we use our own harddisk with 3 different versions of MS windows.
Since Live CD's are capable of running on multiple hardware I was wondering.

Could I install Knoppix but preserve the Live CD properties of checking hardware everytime so I can use the same install for 3 different computers???

The 3 computers currently are:

- HP/Compaq P4 HT 2,8 GHz intel 915 chipset
- Dell™ OptiPlex™ GX240 1,7 GHz P4 probably also intel chipset.
- Last and most sertainly least important because there aren't that many of these Fujitsu Siemens no idee about the mobo 2,4 GHz P4
(They all use onboard Ethernet, Graffics and sound (I don't really care about the sound)

So could I use 1 install of Knoppix or any other Linux you van reconmend for booting op all 3 systems.
I'm relatively new to Linux, I only tried 3 distro's so far and can't live without a dual boot with XP (for now).

At home I just passed the barrier of using Linux more then Windows but I have to use Windows at school all the time I might revert to Windows.
Because I spend about 5 hours on school computers a day and maybe 2 home.

And because we mainly work with VMware and stuff at school that is not a problem (is it????, I never tried it with Knoppix)
