It is an old cdrom from 1991 with a caddy, and maybe 2x speed. I've checked and FreeBSD has a driver for the cdu31a, which is very similar but is different enough not to work. There is a Linux driver for both cdu31 and 531, and I thought I could create a driver for Freebsd by examining the differences between the two Linux drivers, and applying this to the existing FreeBSD 31a driver. The equation would be: Linux(cdu31a) - Linux(cdu531a) + FreeBSD(cdu31a) = FreeBSD(531a) I might try to do the driver myself, but thought I might see if anybody already did this, and evaluate the driver. Also, I'm looking for any helpful hints on how to test out a driver without actually recompiling the kernel and rebooting - sort of a main() wrapper for the driver source. Of course, the driver would have to be given a new device node name to differentiate it - "scd0" is the name of the existing cdu31a driver, so maybe "scdu0" would be a good name for the cdu531a driver.
