It`s possible, but not straightforward.
If you`re using 3.0 Roms, then you can`t cold boot from a CD, as it doesn`t have the driver or CD filesystem in ROM. So you`d have to boot to the floppy or HD, load them into memory then reset.
AFAIK, the 3.1 ROMS have a CD filesystem, but not the ATAPI drivers, so you`d still need to load up IDEFIX or whatever.
