i m talking about the matsushita (?) cd rom 562b type. i have a special controller for it in dos, but when i want to work with linux, and mount the cd, i must connect the cd to the soundblaster. I tried to work with the cd in dos, connected to the SB, but then the dos doesn't recognize the cd!! does any one know, who can i use this CDR-562b under dos, connected to SB? ira? DORON.
