Tyson" 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): , 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''?
