Mark --
Your original suggestion (leave controller wcd1 enabled) was
right. I thought I had done so, but in fact I had only left the
disk (wd1) enabled, not the controller.
Here are the relevant lines from the HOMEBASE configuration file:
controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr
disk wd0 at wdc0 drive 0
disk wd1 at wdc0 drive 1
controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr
disk wd2 at wdc1 drive 0
#disk wd3 at wdc1 drive 1
options ATAPI #Enable ATAPI support for IDE bus
options ATAPI_STATIC #Don't do it as an LKM
device wcd0 #IDE CD-ROM
Here are the relevant lines from dmesg:
wdc0: unit 1 (atapi): <CRD-8160B/1.04>, removable, accel, dma, iordis
wcd0: 2734KB/sec, 128KB cache, audio play, 255 volume levels, ejectable tray
wcd0: 120mm data disc loaded, unlocked, lock protected
wdc1 not found at 0x170
Any hints on how to fix the ``wdc1 not found at 0x170''?
Thanks for your help.
