Is there a trick to installing with a : Mitsumi drive? Any pointers would be appreciated. : Elizabeth The Mitsumi CD-ROM drives are only supported at a few i/o ports and IRQ's. I don't have my lizard book handy but you can find the info on what i/o ports are probed for Mitsumi's in the book. If you are able to change the CD-ROM settings to the ones in the lizard book you should have no problems. If not you may have to do things the hard way. My install of BSD/OS v2.0 with a very old single speed Mitsumi CD-ROM was quite an experience. First the interface card was soo old I had forgotten how to set the jumpers. Well I knew what port it was at (by using DOS) but BSDI just would not recognize that port address. The only way I could get it to work was to get to an existing BSD/OS v2.0 machine and compile a kernel that had the right settings for my CD-ROM. Then I made a copy of the first install disk and moved this new kernel image onto it. The install saw my CD-ROM when I re-did the install and everything else worked okay. If you are still unclear or if you do not have access to another machine, e-mail me and I'll see what I can do. later. ---------------------------------------------------- Mark Zander mark.zander@sheridanc.on.ca Technical Support Sheridan College (905) 845-9430 ext. 2166 1430 Trafalger Rd (905) 815-4011 fax.
