I can provide the drivers but the first thing you would have to do (if you haven't done it already) is to install the custom firmware. This being an HD you would also need a USB hub which should be externally powered if the drive itself is not externally powered.
I should add that there is no guarantee this will work, the main area of uncertainty is whether or not it will appear as a device on the system. You can test this by connecting the optical drive (after the system has booted) with a disk inserted and typing the following at a telnet prompt:
Code:
hexdump -n 512 /dev/sdb > /dev/null
This should just return a prompt with no error message. However, if the error message "hexdump: /dev/sdb: No such device or address" is returned then it doesn't look very hopeful. BTW This assumes that you have another disk connected at the same time using the hub and containing the mod.
Note that the drives (hard disk or optical) are usually allocated names in the order that they are found by the system. The first drive will be /dev/sda, then /dev/sdb etc. This is why it is important to connect the optical drive after the system is booted for this test.
