>Number: 6652 >Category: kern >Synopsis: QIC80 Tape drive (ft0) not probed using embedded FDC on Pentium m/b >Confidential: no >Severity: non-critical >Priority: low >Responsible: freebsd-bugs >State: open >Quarter: >Keywords: >Date-Required: >Class: support >Submitter-Id: current-users >Arrival-Date: Sat May 16 03:10:01 PDT 1998 >Last-Modified: >Originator: Neil Kefford >Organization: - >Release: 2.2.6 (Also verified on .2 and .5) >Environment: - >Description: When using a Colorado Jumbo 250 tape drive (QIC 80) on a 486 with a multi I/O card (HDD,FDD,COM etc) the device probe at boot detects the drive as device ft0. On switching to a Pentium m/b with embedded controller the device is not detected. The DOS TAPE.EXE detects the tape drive in either configuration. If I disable the embedded FDD controller and install a separate controller card, the drive *is* detected! There must be something different about the embedded controller! FreeBSD cannot probe it on this controller, but TAPE.EXE can find it. >How-To-Repeat: M/B is a Gigabyte GA586 HX (although I suspect any pentium m/b will do it) Boot with tape drive connected to embedded controller and compare to boot with separate controller. >Fix: Install a separate controller card just for the floppy and tape drive! >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
