I recently found an old ISA CD-ROM controller and decided to put it to my 486DX2-66 build (DataExpert 4407 v1.3 board, Cirrus Logic VLB graphic card with HDD/FDD/serial/paraller controllers) While the CD-ROM lights up and operates just fine, I'm completely unable to configure it, either via the oakcdrom/mscdex or shcdx/xgcdrom drivers (both return that no CD-ROM drives were found). Trying to load them via the standard DEVICEHIGH/LOADHIGH command and /D:MSCD001 name

I admit, I don't have much experience with the CD-ROM in 486 systems, so I'm not sure whether I'm doing something wrong, or any additional card driver is required to be loaded before the CD-ROM one.
