kernel 2.2.1, taper and Colorado 5GB IDE TBU

Post by John Thompso » Tue, 09 Feb 1999 04:00:00



I have just finished compiling kernel 2.2.1 and am trying to
use taper with my Colorado 5GB IDE tape drive.  The kernel
appears to recognize the drive, as evidenced by
/var/log/messages:

Feb  8 11:53:30 starfleet kernel: ide0: BM-DMA at
0xf000-0xf007, BIOS settings: hda:pio, hdb:pio
Feb  8 11:53:30 starfleet kernel: ide1: BM-DMA at
0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
Feb  8 11:53:30 starfleet kernel: hda: WDC AC26400B, ATA
DISK drive
Feb  8 11:53:30 starfleet kernel: hdc: 36X CD-ROM, ATAPI
CDROM drive
Feb  8 11:53:30 starfleet kernel: hdd: HP COLORADO 5GB,
ATAPI TAPE drive

When I try to use taper ("taper -T ide") the drive appears
to respond correctly but always eventually fails with a seg
fault:

---clip from taper_log---
Mon Feb  8 12:11:47 1999:  Backing up file
/home/skylar/Office50/config/nedland.bmp; actual size 29808,
on tape size 29808.
Mon Feb  8 12:11:47 1999:  W: Child Segmentation fault

When starting taper I do get some messages from the ide-tape
driver to the effect that a speed setting is not properly
configured:

Feb  8 12:04:25 starfleet kernel: ide-tape: hdd: overriding
capabilities->speed
(assuming 650KB/sec)

Perusing ide-tape.c suggests that this may be a quirk of the
Colorado drive and that by using "speed == 0" one may
overcome this obstacle:

 * Ver 1.13  Jan  2 98   Add "speed == 0" work-around for HP
COLORADO 5GB

But it is not clear to me how, or where this change is to be
made.  I'm not a programmer; I don't know c from Martian so
take it easy, please.  I feel like I'm making progress (at
least the drive responds now) but I'm not there yet.

Thanks...

Recompiling the kernel with the ATAPI/IDE tape driver doesn't work?
