Very Computer

I have a multission cdrom with an open link (I will write other
informations on). MSCDEX (the MICROSOFT Dos driver) handle this cdrom
without problem, but /dev/mcd doesn't recognize it.

I have spent a lot of time last night for upgrading my old 1.1.18 kernel
in 1.2.13 because I want use a new /dev/mcdx driver.

This driver don't handle my cdrom and I want understand why.

I search any information on
       1. ISO9660 format
       2. Mitsumi FX001D instructions

Thanks for your help
