Has anyone successfully added an IDE-based CD-ROM drive to an otherwise all-SCSI system under FreeBSD 2.1.5? The box in question is built around an ASUS 486 motherboard, an SP3G. I've added ASUS's PCI SC200 host adapter, which uses the NCR 53c810 chip, in order to have an external SCSI port. The host adapter talks to a Seagate drive and a 4mm Hewlett-Packard DAT tape drive. A second PC, with only an IDE hard drive and a Mitsumi FX400 IDE CD-ROM drive, had run successfully under FreeBSD 2.1R with its "atapi.flp" boot image for the original installation. My hope was to move the Mitsumi CD drive to the SCSI box for use with 2.1.5, and, given the results under 2.1, I expected the move to be painless. However, I cannot get the SCSI-based box to recognize the CD-ROM drive. The Mitsumi drive is the only device on the (built-in) IDE bus and is jumpered to be a Master device. The IDE controller is enabled in the ASUS setup and is recognized on IRQ 14 by the "boot.flp" image. Sadly, the boot diskette under 2.1.5 never finds a "wcd0" device. When a normal installation attempt reaches the point at which it needs to read from the CD, I get a "No CD drives found" message. Similarly, attempts to mount the CD by hand from the fixit floppy result in a "device not configured" message. (This same physical drive worked under FreeBSD 2.1 on the other PC, and it works under DOS on this ASUS-based PC, so I'm reasonably sure the hardware is okay.) Anyone have any suggestions for grafting an IDE CD-ROM onto a healthy SCSI box?
