I recently got few old Creative CD-ROMs and SoundBlaster 16's. One interesting was that there is Sound Blaster 16 CT2910 which has Panasonic interface without header and one Creative CR-563-B CD-ROM with Panasonic interface. Why and should I try to connect, why not. After carefully opening solder pads, I put 40pin header and soldered it. Put in test computer. Installing SB16 software, card seems to be working as it can play audio. Then added cdmke.sys to load cd but it fails. Cannot find device. Also tried with sbcd.sys but same result.
Beside IDE interface, there should be three resistor packs. Some of the resistor pack contacts lead to Panasonic interface, should there be resistors? And if should, what could be resistance?
Also wondering, does IDE interface needs to be enabled or disabled when using Panasonic?
Test bench is plain 486 with Multi I/O and VGA card. IRQ/DMA does not overlap with anything. Tried different IRQ/DMA options, still all others are working but not CD.
