The Debian installation system permits loading of third-party drivers.
You need some way of booting of course (e.g. CD, floppy, or network).
With floppies for example, as long as the boot floppy supports your CPU
and floppy drive controller you're good to go. Once the kernel is
loaded, it'll ask for a root floppy with ramdisk image. After that's
loaded the installer starts, but Alt-F2 will take you to another VC as
usual. From there you can mount any floppy you like and insmod any
module it contains.

RedHat must offer something similar. Adaptec provides driver disks and
installation instructions for installing RedHat on Adaptec controllers
which RH doesn't support natively. (For example, the aic79xx
controllers before that driver made it into the mainstream kernel.)

You may not get *prompted* to install third party drivers (at least some
installers do, though) but the lack of prompting does not mean that you
can't do it.
