I've had almost the exact same problems (sorry no fix yet). I have
|
|
noticed in the message file (/var/adm/messages) that ftape finally
|
|
chokes when it gets an error trying to write to the header. I think
|
|
this is occurring after successfully updating the header numerous
|
|
times since I have a flood of the same previous "error sector #/
|
|
reposition") messagesjust before it finally chokes. Anyone got
|
|
ideas on this?

Supposably there are going to be some Digiboard card drivers soon.

You might want to check with them also for multi-port cards to run

Subject: Anyone using multiport boards? Such as digiboard or BOCA?
|

Date: 6 Oct 1994 00:59:08 -0500
|
|
|
|
I would like to add a multiport i/o board (or two or three) and use
|
|
Linux with 16 or more dial-up modems. It seems that the digiboard
|
|
is not yet supported. Has anyone used the BOCA card? Or perhaps
|
|
the BUS6, or even the AST Four-Port cards?
|
|
|
|
If anyone has this working, how well does it all work when sixteen or
|
|
more people are all doing file transfers and I am compiling AND using
|
|
XWindows AND playing DOOM? Obviously, I am demonstrating a worst case
|
|
scenario, but I just want to be sure that my system works well under
|
|
stressful times.
|
|
|
|
Also, would 16 meg of ram be sufficient? Or will I need to go higher?
|
|
I will not be running shell accounts or applications. I will merely
|
|
be an ftp site with some dialup access for local slip users.
|
|
|
|
Any advice will be greatly appreciated. Thanks.

I had the same problem, and the immediate cause turned out to be that

I was using the root diskette that is companion to the installation

diskette, rather than the installation diskette itself. (MCC distribution).

I think this limit is at 527,966,208 bytes. This is based on a maximum
|
|
of 1023 cylinders (number of cylinders limited to a 10 bit field by BIOS),
|
|
63 sectors (number of sectors limited to a 6 bit field by BIOS), and 16
|
|
heads (although BIOS allows up to 255 in an 8-bit field, the field in the
|
|
disk command structure is 4 bits). You may see 527MB stated by those
|
|
who use 1,000,000 as the divider (it makes disks look bigger) or you may
|
|
see 503.5MB by exactness nuts (like me) who use 1,048,576 as the divider.
|
|
You may also see 512MB by those who miscalculated (unless there is some
|
|
secret to getting 1024 cylinders and 64 heads out of the BIOS that I am
|
|
not aware of).
|
|
|
|
In any event, if the ENTIRETY of your DOS partition is below this limit,
|
|
DOS will not need any special drivers. FDISK should be able to partition
|
|
it OK as long as it does not try to actually do I/O to the partitions.
|
|
|
|
Since BIOS is used to boot with, including booting from LILO, everything
|
|
needed during boot must also be below the above limit. If your kernel
|
|
image happens to get located below the limit in a full disk filesystem,
|
|
it will probably load OK. If you update your kernel it may be relocated
|
|
above and cause problems.
|
|
|
|
If you want the biggest possible filesystem, one solution would be to
|
|
make a small kernel image sized partition (leave enough room for future
|
|
enhancements) which can either be booted from LILO or marked as the boot
|
|
partition and booted directly. If you make it partition 1, do the fdisk
|
|
in sectors (with the "u" command) and start it at sector 2 instead of 0.
|
|
You will get warnings about cylinder boundary stuff... ignore them. Now
|
|
when you change kernels you only need to use "dd" or even "cat" to copy
|
|
the kernel image into that partition.
|
|
|
|
BTW, while you are repartitioning, if you do stuff with floppies a lot,
|
|
you may want to create a handy floppy sized partition (use sector mode
|
|
in fdisk for this, too). If I am creating a bunch of floppies for stuff,
|
|
it is faster to build the floppy image by mounting that partition as an
|
|
MS-DOS one, putting in the files as needed, unmounting, and saving the
|
|
image (as a file somewhere or direct to a floppy). I did this when I was
|
|
downloading the latest Slackware. It made things go a lot faster.

SCSI: The original standard. Sort of. Not everything has thesame

level of compatability..so it may say 'SCSI' but it may not work.
|
|
SCSI-2: Much closer to a standard. It's reasonable to assume that

something that says 'SCSI-2' on it will work with yr machine.
|
|
fast SCSI-2: Transfers 15M/S? Faster bus.
|
|
wise SCSI-2: Doubles the bus size, allowing faster transfers. (16bits?)
|
|
AV-SCSI: Fine-tuned for use with multimedia where you need a
|
|
consistent transfer rate. Most IDE and SCSI drives will need
|
|
to 're-sync' the heads physically every now and then, resulting
|
|
in a pause in the transfer. AV-SCSI drives don't need to do this.

You forgot another good reason to go with SCSI. The PReP compliant

motherboards Motorola released today are supposed to have SCSI-II
|
|
controllers on them. I smell a port in the air.
|
|
I only have to pickup one tape drive to share between systems, and

I can always use Intel linux for putting trial bootstraps and filesystems
|
|
on harddisks.

In my experience, if all you want is a single machine, that isn't going

user environment.
|
|
|
|
If you plan on running UNIX 24hr/7day, you should invest in SCSI. SCSI
|
|
eats up less cpu bandwidth, and is faster to the user. SCSI is more
|
|
"intelligent" then IDE in the sense that things can be offloaded to the
|
|
controller as opposed to the main cpu. In the case of DOS this is
|
|
pointless as DOS waits for everything to finish before letting you
|
|
continue anyways, but in unix, it allows more efficent multitasking.
|
|
|
|
So, if you plan on doing many multitasking things, then go with SCSI and a
|
|
good controller, 1542 (or clone) for example. But if you just want more
|
|
space to play with unix, and maybe do some stuff, stick with the cheaper
|
|
IDE.
|
|
|
|
Swapping on IDE is horrible on my machine. I have 32 megs of memory, so
|
|
I get lots of buffers, when update writes the buffers every 30 seconds, I
|
|
would get 2-3 seconds "freezes" while this was done, and the drive was
|
|
written to. I suspect that this happens less if you have 8-16 megs of
|
|
ram, or in my case, I switched to a scsi drive for swap, and things are
|
|
much better. (BTW, I had a dedicated swap controller/drive, and I still
|
|
had this problem.)

Hmm. One of the previous versions had an end-of track problem.
|
|
Essentially, it went looking for a sector that wasn't there and
|
|
forgot to reset the FDC when it failed. I sent Bas a fix then
|
|
(sometime back in jan/feb or thereabouts) but he replied that
|
|
the problem had been fixed in another way. Perhaps it's crept in
|
|
again? Forgot details, looking into it during the weekend.
|
|
|
|
If it goes on at multiples of 160 (?) sectors, this is likely
|
|
to be the cause.

Doubts. My USR-DS 16.8 Fax supports 57600, I don't think it makes any sense to
|
|
set the DTE rate higher. May you're using one of the new pieces which already
|
|
support 115200..

A HD "starts" as soon as you turn on the computer or the actaul HD (if it's
|
|
an external). There is no way to turn off the power unless you unplug the
|
|
HD.

HD are sometimes like cars, lemons do get into the market. But the majority
|
|
of HD won't see their death for 5+ years of continuous use. HD don't really
|
|
wear out, although the media may form defects. If the media can still
|
|
function, the motor will be the first to die. Motor lifecycles range from a
|
|
mean of 3.5 to 7 years.
|
|
|
|
The worst thing for a HD is the fluctuation in platter tempature and shock.
|
|
If your computer is always on and never violently shaken, it will live out
|
|
its lifespan.
