CR801/3Q version 2.1 For US brand Calix 44X. On boot, bios reports drive as "CR-801Q". Normal install in config.sys. Runs under DOS/Win9x. Friend had one of these drives with factory floppy. The LiteOn driver on your site that works for a 32X LTN301 works on this drive also. That driver might be better/newer as it is larger file size, newer, and claims to work for all LiteOn drives.
