Most install CDs these days can either be booted, or have the appropriate images already on the CD. For instance, if your computer can't boot directly from CD and you wanted to install RH7.2, you could boot into Windows and use the
rawrite util that appears in the D:\images directory (presuming the cdrom is on d
.
In answer to the 1st question though (how to make a 2.2.17 boot-disk)...when you configure and make the kernel, you can type
make bzdisk as well as
make bzImage. This should make a kernel-boot-floppy. I suppose, if you really wanted to, you could boot from this, mount the CD and chroot to it and install that way, but it seems to be making life hard when almost all distros (Debian included) have really good instructions on how to make a install-boot-floppy.
Hope this helps.
