Try PlopBootmanager (a few kb).Thanks, the mini-DVD idea is tempting but I'd have to go with a mini-CD as some of the machines I maintain still only have CD players.
The USB sticks are nice too - but only for machines that can boot usb. Most of my machines can't unfortunately Sad
I think I will have to stick with the business card CD method for now.
You can boot from cd and then select the boot device (cd, usb, hd etc)
PlopBootmanager has all needed drivers included.
I do use this on one old computer that can not boot from usb.
Edit: I do have an iso, but it is too big (2356 kb) to post this one here. I will upload this to my mediafire account and then post the link here within the next 4 hours - if possible (i am an a slow connection now).
Edit: I see, it is not necessary to upload this iso. There are several links on the web. Try "Plop Bootmanager" for search anywhere (but not google)
Hope this will be the needed solution to you.
