Our news was down so this might be a repeat but doubt it. I have built a Compuadd 386/25 MHz with a scsi disk hanging off the WD7000FAST controller. Unix runs(Intel V.4 vs 2.0) as well as can be expected with 4 Meg. I have a good Exabyte 8200 that I have placed both at id 2 and at id 5 on the SCSI BUS and upon booting, It says that it sees an Exabyte(Probably data from an inquiry) and that since it is not supported, it will not be configured. Since I wish to develop from X I am not buying more memory until I either get this to work or uucp(also a problem). The support number says that since I did not buy $2000 contract and I am running have to go through Avnet for support. I assume since the support manager says they had some Exabyte probelms other than this. That either another SCSI controller supports it(probably the 1541b adaptec) or there is some configuration item I am missing. Help via EMAIL would be wonderful. The UUCP problem is the infamous DEVICE UNAVAILABLE. I have what worked well for V.3 and made uucp owner and group. ??????? The other entries shouls work in Devices, Dialer, and Systems. Email please

The problem is that AT&T in it's infinite wisdom has placed a hard-coded table into the kernel of the devices that the system will support. This table is located in /etc/conf/pack.d/sd01/space.c. Each entry in the table has two pieces of information. The first piece is the EXACT string returned by the SCSI inquire request. This will be displayed by the os when it tells you that it doesn't know about the device. You must copy it down exactly including spacing, upper/lower case, punctuation. The second piece is the number of "LUs supported by the TC". I don't really know what this is, but for 99.9% of the SCSI devices out there it will be a 1. So to get your tape drive working add a line to the table that says something like: "Exabyte id string.... ", 1, /* Exabyte 8mm tape drive */ > Help via EMAIL would be wonderful.

Some like the Emulex MD/21 will talk to 2 Esdi drives. And some like the Scientific Micro Systems Omti 7400 will talk to 2 esdi or st506 drives , 4 floppies, and a streamer tape. |> So to get your tape drive working add a line to the table that says |> something like: |> |> "Exabyte id string....

The sdo1 directory was for hard drives and there was one I think called st01 which when I placed the entry enabled the device /dev/rmt/c0s0 The UUCP entries are set up and if I go "cu sleaze": It finds the line, the modem, the dialer, dials the phone and even connects correctly. While spiiting lots of debug messages to the screen. plain "cu" gives me a "CONNECTED" message but I can not control the modem and dial. uucico never gets the phone dialed. ??
