For manually insmodding a driver when you have the driver but don't have a driver disk.
Start the install
Do not select the driver in question from the list
Once you get connected to the 2nd stage install then switch to the available BASH# prompt on vt2 (ALT+F2 or CTRL+ALT+F2)
Access your vfat (msdos) or ext2 floppy: "mknod /tmp/fd0 b 2 0; mkdir /floppy; mount /tmp/fd0 /floppy"
Now insmod your driver with any parms you need: insmod /floppy/cpqarray.o eisa=0x4000
unmount your floppy: "umount /floppy"
Now switch back to your installation on vt1 (text mode install) or vt7 (gui mode install)
Your drives should show up or you may need to go forward or back one screen.
Continue the install as normal. The installation will not know anything about your driver so you will have work to do at the end of the install.
At the "congratulations screen" switch back to the BASH# prompt on vt2.
chroot /mnt/sysimage
su -
you can access your floppy through: "mount /mnt/floppy"
Your updated driver goes somewhere into /lib/modules. If you don't have a new driver for the regular kernels then install the kernel-BOOT rpm (maybe disc3) and then put your installation driver into that kernel tree (in /lib/modules).
If your boot drive is one that is supported by this new driver then you must check modules.conf and make a new initrd.
modules.conf should contain an "alias scsi-host-adapter cpqarray" and an "options cpqarray eisa=0x4000" or similar for your storage drivers.
Now that modules.conf is updated, create a new initrd. "/sbin/mkinitrd /boot/mynewinitrd 2.4.18-14" (You get the kernel version from /lib/modules).
Now do a final check with your boot loader (LILO or GRUB) to make sure that it can point to the right kernel and your new initrd. If using LILO then be sure to run "/sbin/lilo -v" to commit the changes from /etc/lilo.conf.
unmount your floppy: "umount /mnt/floppy"
exit from "su -": "exit"
exit from "chroot": "exit"
cd /
You're done, switch back to vt7 and press ok on the "congratulations" screen.
