The burgess faqs pages state that there seems to be some trouble getting mitsumi drives to work. The FAQS mention editing mcd.c to force a certain return value from the mcd_getreply() function. I do not feel quite up to this task. I am not sure that it is exactly necessary yet. Here is some info from files in my system. Note the error messsage for mcd0 **snip /var/log/messages /kernel: fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa /kernel: fdc0: NEC 72065B /kernel: fd0: 1.44MB 3.5in /kernel: wdc0 at 0x1f0-0x1f7 irq 14 on isa /kernel: wdc0: unit 0 (wd0): <ST32140A> /kernel: wd0: 2015MB (4127760 sectors), 4095 cyls, 16 head **yadda /kernel: wdc0: unit 1 (wd1): <ST3243A> /kernel: wd1: 204MB **yadda /kernel: wdc1 at 0x170-0x177 irq 15 on isa /kernel: mcd0: timeout getting status /kernel: mcd0 not found at 0x340 **snip **snip /KERNEL #ADMIN These controllers are arranged as follows inside the machine. # the 2 gig drive is master the 240 meg drive is slave. both are # connected to the onboard pci-ide controller socket that is labeled # IDE1 in the mother board manual.

This CDROM is IDE compatible. Based on that... Do I need the mitsumi driver? It seems like this answer should be yes. Why can't I hook it up in this manner? disk wd2 at wdc1 drive 0 Why can't I hook this up in this manner? device mcd0 at wdc1 drive 0 Why won't the drive wcd0 work? When I try to mount it it says "device not configured" This device wcd0 does not show when I "lsdev" even thought it is compiled into the kernel. BTW, lsdev will show that mcd0 exists but says not configured int the status column. lsdev does not show device wcd0 at all. I have trial and errored and even kernel paniced myself into submission on this one. Oh yeah, I read all of the wrong documentation in search of an answer. If you could point to the right docs that would be a great help. If these questions don't help me to get to my objective then I ask this final question. How the hell do I get this drive to work?
