I don't understand what you are saying.

For BL3 you need to insert three modules to use the CD-ROM drive, then you 
mount the CD-ROM (/dev/hdc), read from it, and umount it before you remove 
it. For USB sticks you need to insmod some scsi and usb modules first, 
then mount /dev/sda4.

With my latest kernel you don't need the modules but you still need to 
mount either of these.

Do you want ide-cd.o instead of built-in support?

Didn't he automatically mount the USB stick at boot?

Okay.

I did that and uploaded bzimaglc.431 in ./2.4.31

I was trying to fit into the existing 4MB RAMDISK.

Thank you for pointing out the confusion.

These are all compiled into the kernel now.  So are the cd-rom modules 
including sr_mod and sg, and I think also ide-scsi (for scsi emulation).
