Hi,
I am not a subscriber to this mailing list, so a direct response (along
with a posting, naturally) would be greatly appreciated.
I am using Caldera OpenLinux 2.2, which comes with ftape/zftape 3.04d.
As root, I can do an <mt (or ftmt) -f /dev/nftape retension or
rewind>. However, when I try to do an <mt -f /dev/nftape erase or
fsf 2>, I get tape movement and a "/dev/(n)ftape: Permission denied"
on the device. Further, when I do <tar -cvf /dev(n)ftape ...>, I get
"Cannot write to /dev/(n)ftape: Permission denied." I checked the
permissions on /dev/{n)ftape and they are 600 (/dev/(n)ftape is a soft
link to /dev/(n)zqft0) and are character devices. I have modified
the permissions to be 666, but get the same results. Also, I get the
same results with /dev/(n)qft0. I am using the COL 2.2 provided
ftape.o and zftape.o kernel modules, which get installed during boot.
I see nothing out of place in the messages generated during the
installation process.
I looked in conf.modules and found that the defined ft_fdc_base=0x180,
but that /proc/ioports does not list the floppy controller, or anything
else, at 0x180. I noticed that ft_fdc_irq and ft_fdc_dma values did
not match those in /proc/irq or dma for the fdc, so I changed them to
be consistent, but to no avail. There is nothing in ioports that one
could connect to the fdc base address, except maybe fdomain at 0x140.
My hardware manual and the old MSDOS diagnostics do not provide me
with any information about the base address for the floppy disk
controller. I have also tried ft_fdc_base=0x3f0, but the same
results. I have not been able to determine what fdomain is, so I
have not tired its address.
I used to have an UMSDOS version of Linux (1.2.8, I believe) and had
ftape working fine under it.
I have looked at the HOWTO, FAQ, the Installation & User Guide, but
see nothing to guide me. I would really like to get my QIC-80 tape
drive to operate. Can someone provide me with assistance?
Since my kernel version is different from the tools distribution, I
have not been able to run ftformat on the tape, but I believe the tape
has been previously formatted (but am not absolutely sure, since the
system no longer contains MSDOS). I plan to build the tools once I
get the rpm source downloaded. That should move me up to ftape 4.02,
but I am not sure that will help me. Anyway, ...
Thanks for your help,
Chuck Burton
