Ecrix VXA-1 tape drive and FreeBSD 4.5

[Martyn Hill]

Hi

I've never yet managed to get a solution to the following problem, but
thought I'd try one last time before ditching the Ecrix tape we bought last
year...

We run FreeBSD 4.5 RELENG on our fileserver (sjserver) and I have installed
an Ecrix VXA-1 tape drive (IDE) on the secondary on-board IDE controller.
The system has an additional E-IDE controller. The following message snip
appears in /var/log/messages:

device - NO DRIVER!
Nov 25 20:53:01 sjserver /kernel: acd0: CDROM <CRD-8320B> at ata1-slave
using PIO4
N

The kernel has been compiled with a config file that has what I believe to
be the appropriate drivers:

# ATA and ATAPI devices
device  ata
device  atadisk   # ATA disk drives
device  atapicd   # ATAPI CDROM drives
device  atapist   # ATAPI tape drives
options  ATA_STATIC_ID  # Static device numbering

Q1: With reference to the line above that end "NO DRIVER!" - what exactly
does this signify? I wasn't aware that a particular driver was required for
an IDE drive.

Q2: Has any one used this IDE device successfully and could forward their
solution?

Q3: What dev number would be required/used for this device (ad2,
ata1-master)

Q4: Is it the combination of Tape-drive and CD-ROM on the same controller
likely to be the cause difficulty?

As always - any assistance would be very welcome!
