Subject: Ftape compiles fine, fails to function correctly.
Date: Sun, 06 May 2001 07:14:47 GMT
I decided to resurrect the old floppy tape drive I have. I don't recall the
brand or specific model any longer (can't find the box, bought it several
years ago, Ftape ID's it as a Conner TSM420R/TST800R). While I got Ftape to
compile without error, it fails to function correctly.
Setup data:
* 486DX4-100
* 16 MB RAM
* 1 floppy drive, rarely used
* Tape drive
* 2.5 GB IBM IDE HD
* 16-bit ISA IDE/floppy/serial/parallel interface card
* ISA VGA card
* 10/100 PCI Ethernet card
* Redhat 6.0 native installation (kernel 2.2.5)
Problem:
I can insert a tape and the drive responds appropriately, doing whatever it
does to set it up for use. When I attempt to get a status off the drive, it
fails with "ftape-rw.c (ftape_wait_segment) - fdc_interrupt_wait failed."
It communicates with the drive, because the drive winds the tape to the end,
then rewinds it back. Unless I put a halt to the status check, it continues
this way in a never-ending fashion.
I have not attempted cleaning the heads. I did unplug and replug drive
cables. The drive is on a separate power connection -- that is, it isn't
"Y"ed off of anywhere. I've read the FAQs about checking the DMA memory
areas of the VGA and Ethernet cards. As far as I can tell, there is no
conflict. The VGA card isn't PCI and the DMA memory addresses appear far
off the FAQ's warning areas.
The floppy controller chip is identified as 8272A/765A. The maximum FDC
supported data rate is identified as 500 Kbps. It always identifies the
floppy controller correctly (0x3f0, IRQ 6, DMA 2), although I did try
putting it in my /etc/conf.modules just for grins. The floppy drive
functions correctly. I no longer have any idea where the original DOS
software is and cannot try the tape drive under DOS.
I looked through the old Dejanews (now Google) newsgroup records. Most of
the fdc_interrupt_wait entries (more than 90%, truly) are people who had
problems getting Ftape to compile through that segment of code. For me, it
compiled just fine. It's just not functioning correctly.
As the actual logs are fairly long, I am holding off posting them. However,
I know how important logs are, so I can make them available if they are
necessary. Right now, I'm hoping that someone will recognize this problem
and be able to say "you need to insert dongle A into drive B while doing a
square-dance around device C."
The status command in question:
ftmt --file=/dev/qft1 status
/etc/conf.modules:
alias eth0 eepro100
options ftape ft_tracing=0,6
alias char-major-27 zftape
options ftape ft_fdc_driver=none,ftape-internal,none,none
options ftape-internal ft_fdc_base=0x3f0 ft_fdc_irq=6 ft_fdc_dma=2
pre-install ftape-internal /usr/local/bin/swapout 10

I have a brand new a7v133 motherboard with a 30 gig ata100 quatum hdd on the
ata100 controller primary master. I am trying to install linux on the hard
drive from booting on a homemade linux kernel on a floppy. When booting the
kernel it goes through different hardware driver loads and checks until it
comes to checking the partitions
Checking partitions:
hde
hde: status=0x50 { DriveReady SeekComplete Error }
hde dma disabled (at this point the computer continues to boot using PIO
mode 4 for transfers)
I got this message for a while trying different things in bios and different
hardware configurations. Nothing seemed to change. reset the bios to its
defaults and now the kernel boots till
Checking partitions:
hde (at this point the computer hard crashes)
>From what I have read and what I am guessing is that the timings are off
between the DMA on the HDD and the DMA on the controller. The hard drive is
brand new. I just took it out of its packaging three days ago. I believe
that it is a bad hard drive. I tested the computer with a western digital
ata66 20 gig hard drive and that had no problems.
could anyone confirm exactly what the problem is and if it is infact a
bad/failing hard drive.
Thanks,

PS. The hard drive appears to work perfectly in pio mode.

It should work fine as ATAPI TAPE or ATAPI DISK. Try to load the kernel
module or check "dmesg" after booting if the drive is recognized.
Maybe you must mount the disk as hdX4 such as the ZIP disks. The rest
should be equal to the SCSI thingie.

Subject: avoiding USB support at start-up
Date: Sun, 06 May 2001 09:13:13 GMT
Dear community,
Some time ago I have upgraded my linux distribution to include USB support,
with kernel 2.2.16 from the Red Hat 7.0 distribution. Then I bought a USB
Iomega Zip Drive, 100 Mb, that I planned to use on my Toshiba Tecra 720 CDT
laptop. Later on I was told that in order to use the usb-storage module I
needed to upgrade to kernel 2.4.x, so I compiled 2.4.2 with kgcc and making
sure that all the packages needed were up to date.
Despite the support received from several newsgroups, I have had little
success, as I am still unable to mount my zip drives.
The main problem is that, approximately 70% of the times, my laptop would
not boot at all, freezing when loading the usb-ohci module (I have a NEC
Corporation USB controller, rev 01) or, if that step is passed, it
freezes when mounting the USB filesystem, or later, when checking for new
hardware. Some times I have to try booting my laptop 6 times and more before
I can start working. If the machine boots, I can work happily but loading
all
the relevant modules and mounting the drive has no effect.
I have decided that, on a temporary basis, before I manage to dedicate some
time to study what is needed to sort out al these problems, I should let my
laptop boot smoothly, thus I would like to remove USB support completely at
start-up. I am sure there is a way out, but I have invested so much time to
date that is time now to meet the deadlines for the work that I have got to
do.
I don't know whether this has to be done by Kudzu, by chkconfig or what.
Could anyone please help by telling me how to control hardware support at
start-up?
Thanks in advance

Right. The V 2.0 of that card does not work with the standard
HiSax drivers, as the layout of the card has changed drastically.
At this time, there is no driver for the Fritz!PCI 2.0 card
at all.

You might want to try the Linux CAPI from AVM to get it working.
Be aware, though, that this is a binary-only solution, and tends to
completely hang the system at times.
You'd probably be better off getting a used Fritz!PCI card that
does work with the HiSax driver.

The biggest problems now occur not because of the kernel version, but
because of XFree version 4. If you can get XFree version 3.3.6 up and
running you should be OK. And capture isn't very effective yet, because mmap
isn't implemented.

LILO will non-destructively write itself into the MBR. But if you
told it to install itself on /dev/hda1 instead of /dev/hda, it would
have trashed hda1's BR (not MBR): not a problem for e2fs disks, but a
big problem for some others (FAT, ReiserFS, possibly more).
LILO probably made a backup of the sector before it installed itself.
You can restore from the backup using `lilo -u' (you may need to
specify the device name after the `-u', e.g., `lilo -u /dev/hda1').

If something bizarre happened to the partition table, you have two
recourses: you can go through probable sections of the hard disk
looking for signatures; or you can, if you know the exact size
(sometimes easy) of the partition before it was destroyed, rebuild the
partition table using fdisk or whatever.
The first option is a nuisance, so I wouldn't describe it. For the
second, use the same partitioning utility as you used to initially
create the partition. Then give it the same parameters you did
initially. If you did something easy like use one partition for the
whole disk, you're set. If not, guess at the values and keep running
a disk checker (chkdsk, scandisk, ndd, e2fsck, whatever is
appropriate) in READ-ONLY MODE until you don't get any errors. Most
checkers will report if the actual device size doesn't match the
reported (in superblocks or BRs) size. It's very important not to
write to the FSes if you have several lost partitions, as if you make
a partition too large it may start writing data at the beginning of
where the next one should be.
If you put all your filesystems in an extended partition, you can
search your hard disk for some signature (which I don't remember,
sadly - someone else here will know it). The first one you find is
likely to be your extended partition table, and you can then just give
Linux fdisk information on where in the disk it is.
HTH somehow.

Date: Sun, 06 May 2001 18:31:44 GMT
I wish it were as simple as reseating the cable and controller,
but we have done that several times. If there is a silver
lining in all this, it is, in fact, our improved facility in disassembling
and reassembling the hardware!
The 29160 comes with three internal SCSI connectors,
68 pin SE, 68 pin LVD, and 50 pin (and an external
68 pin LVD connector). From the installation guide on the
Barracuda 36ES: "This drive can operate in single-ended (SE)
or low voltage differential (LVD) mode. This multimode capability
provides backwards compatibility so you can use it with or without
an LVD-capable host adapter." It is the only device on the
29160's LVD connector. (We bought the adapter
on recommendation of Seagate's tech support to
accomodate the two old "wide" drives and a new LVD
drive to provide some additional space.)
As presently configured, all devices but the new drive
are disconnected entirely from the SCSI bus.
Significantly, when I hooked everything up--the 29160
SCSI controller, both CPUs, 50 pin SCSI tape drive and CDROM,
two 68 pin SCSI wide hard drives, and the new LVD drive, it all
played together fine under W98. This suggests that there are
no gross blunders in our config. And the entire system except the
new controller and drive have worked well under both Linux and
Windows for at least 5 years, through RH 7.0 with a 2940W
SCSI controller.
My gut feeling is that you are entirely correct, just one setting
somewhere needs to be fixed for it to all to sing.
