I got my Mitsumi CD-ROM three or more years ago. I believe ATAPI CD-ROM interface was not introduced at that time. Actually it is attached to Mitsumi CD-ROM interface card, so I believe it is proprietary one. >> >You might also try moving them to the slave position on the primary >> >controller if they aren't there already; otherwise, alone on the secondary >> >controller. >> >> For ATAPI CD-ROM on my second PC, it is placed on secondary controller >> that is SoundBlaster16 IDE port, and set to master mode.

It is set to the secondary interface default of 0x170 and IRQ=15. >What changes do you make to the kernel to get it working? For Mitsumi, I simply put mcd0 enabled with modifing I/O and IRQ according to my PC. For ATAPI CD-ROM, I did nothing at all. After rebuild kerne with these modification from GENERIC, it is fine. Anyway, thank you very much for your advice. I will work on my problem further, and get in touch with you when I get workaround. Thank you, -- Kenji Owaki owaki-kenji@pa.aix.or.jp
