I LTR-24102B does not work with my Abit KT7. It is recognized by the bios (64) as an UATA-33 CDRW, but the light on it just blinks a lot if a CD is in the drive. You can hear it trying to spin up but it never does. I tried it as PM, PS, SM, SS with and without UDMA enabled with the same result. Weird. I have a Duron 700, SBLive, G400DH,RT8139 based NIC, ATi TV-Wonder, CNET 5614RV pci modem and two maxtor HDs, 512 MB PC133 SDRAM and a Toshiba SD-M1402 DVD in the machine. It works in my work machine, a Duron 800 running on a biostar KL133 chipset mobo with the same DVD drive and maxtor HD. It also works in my mother's K6-2 500 machine with its Via MVP3 chipset. While my AMD approved 300W PSU may be at fault I find it weird that it wirks in other machines. My friend is bringing his machine here. I am going to try it in his machine with my PSU. If it works then there is an issue with my ABIT KT7, and it shall have to be replaced.
