mkinitrd --help

Shouldn't be that hard to understand. mkinitrd creates the initial
ramdisk image which contains kernel modules which can be loaded before
the filesystem is accessible. Easy to understand that when you need a
specific kernel module to access your hardware - typically SCSI modules
are such a case - you can not boot from that hardware because the kernel
does not know to handle that. So you either compile things fix into the
kernel or when using modules you must have a mechanism which gives the
kernel the modules before the kernel is able to access the filesystem to
load the modules from there.

Move the existing initrd image file for your running kernel to not loose
it before processing following:

mkinitrd /boot/initrd-2.6.10-1.741_FC3.img 2.6.10-1.741_FC3

Given you are running the latest FC3 kernel.

If you have more than the current kernel still on your system you can
boot with an older one to be able to access the system again if you made
something wrong.
Else it is easy to use the renamed working initrd image file from grub
boot screen (given you put the old 3ware controller back in).
Last, you can always boot with CD1 into rescue mode and do the initrd
image building correct.
