winnt.sif off a usb key instead of a floppy?

[Leeoniya]

nowadays most computers dont have floppy drives. is there a way to have the winnt.sif file accessed from a usb drive? i know the drive letters might be differet depending on the order in which your bios enumerates the usb ports. but perhaps there is a way to even hardcode the device pnp id or something to have the winnt.sif read off a usb key.

this would be so good, i mean what a waste of time to burn a new image with only the winnt.sif changed for different computer installs.

i guess the alternative would be booting from a usb key, but this seems like a more universal solution, if there is one.

thanks,

Leon
