You didn't indicate what size media you were interested in.
Both Phillips and Sony have announce CD-WORM drives (i.e. ~600 Meg
capacity, cartridges being able to be read on any CD-ROM).

The Sony drive writes double speed (~500KBytes/sec) and costs about $12K.
They are back-ordered up the wazoo; a friend works for a company that
uses them for audio purposes and reports that the first few drives
are temparamental; sony had a older unit that ran for $25K, and eventually
they got the bugs out and were quite reliable.  The problems were almost
all in the firmware, which was easily replaced.  Call 408 information for sony
electronic publishing in San Jose (I don't have the number handy).

The phillips drive could be had for $8500 earlier this summer from a company
called Optical Media, International.  (in cupertino).  I don't have
that phone number either.

What are the optimal setting for an Adaptec 1542D SCSI controller
on a "standard" 486/33Mhz running SYSVR4 (Consensys) ?

We are currently using asyncronus transfer and a DMA speed of 5 MB/s.
Can the performance be improved by altering these settings ?

Thanks in advance !

Hi.

Does any one know how to convert an internal floppy drive into an enternal one?

Suppose I know:

1. The layout of the external floppy drive port.
2. The connector to the internal drive is available.

But, don't have
-  the information about the pins on the internal drive, and
-  the connection for the power to the internal.

Any help is appreciated!

yes, using the dos debug  g=dc00:9  

you can improve the dma speed quite a bit. a test on svr4 unix
with an ast 486 isa, 16mb memory, i got a sustained data rate of 69kb/s
from a dat drive using just a dd cmd.

using the on brd util, i got the dma speed up to the max thereby
improving the same test to 83 kb/s.

your results Will Differ.

Here, here!  I wish they (SCSI vendors) would get their act together
and determine standards!  And device drivers should be provided for FREE.
We paid for them when we bought the card/device!  (You can't tell me the
Adaptec card costs more to manufacture than my i486 motherboard, yet
my i486 motherboard is < 1/2 the price (sans CPU, of course)!)

This is definitely worse than the video fiasco, since you only worry
about 1 device driver with them.  The SCSI stuff needs drivers for
everything (one for the card, one for each device, or one for each
card/device combo).

I had the exact same problem with a Maxtor XT-8760S.  The Adaptec
card simply overwrote some non-volatile information on the drive
and rendered it useless!  It took 6 months to get a warranty fix from
Maxtor!!!!!!!!!!!!!!!!  In the meantime, the price of the drive dropped
by at least 300 bucks.  Oh well, at least it didn't take a whole year
(like the previous time the drive was sent to be fixed).

** This was originally just posted to comp.unix.ultrix but a co-worker

We have some software that dies sometimes while accessing some 8mm
drives.  When this happens, the tape drives become unaccessable.
Attempting to access it will return with "mount device busy". The
only way to clear this up is to reboot the machine.  I would assume
that there is some byte in the kernel that signifies that the tape
drive is still busy but I do not know what it is or exactly how to
access this value to change it.

In the system include file, /sys/io/scsi/mips/scsivar.h, there is a
SZ_BUSY status byte.  It is not clear whether this is for a device
or for the whole SCSI bus.  Even if this is the byte value to unset,
it still looks like a challenge to find where in the structure to unset
this.  Even more challenging (to me at least) is how to find where
this structure starts within the kernel.  I can imagine the sudo code
below but I still have alot of unknowns with no more ideas on how to
get these unknowns.

open (/dev/kmem)
addr of struct == OFFSET_TO_TAPE_STRUCT
remove_busy_bits (struct->some_flag)

   You can acheive (nearly) these rates with disk arrays.  But the real

I'm running a 1542B in a ZIDA 486/50 ( cheapo Tiawan clone ) with a
Digital DSP3085s SCSI-II disk
and Sankyo ES525s SCSI-I tape, sync transfer neg. enabled with BSD/386 (
BSDI ) Unix.

Other cards include an Orchid Pro-Des IIs and a no-name multi-I/O card.

I've had nothing but happyness and joy.

Before BSD arrived I had the system runnig MS-LOSS and DR-DROSS ( only
for a couple of weeks ).

I bought it; I put it in; it worked :-)

This is bound to be caused by differences in the controllers' translation
between SCSI's logical disk blocks and INT 13's requirement of cylinders,
heads and sectors.  Future Domain gives a disk 17, 34 or 63 sectors per
logical track, then fits the number of heads and cylinders to match the
disk's actual capacity.  If the Adaptec doesn't give your disk the exact
number of logical tracks/heads/sectors as the Future Domain, you'll have 
problems.

You're doing nothing wrong.  Future Domain deliberately cripples their BIOS
to limit you to a single SCSI disk so they can sell you their disk
partitioning software.  I've developed a patch to the ver. 6.0A BIOS that 
removes this restriction, as well as halving the boot time and fixing another
problem or two.  Of course, this won't do you any good unless you have access
to an EPROM programmer.  I'll post a notice here when I make it available.

  The idea is that OS/2 would have built-in support for the 1542. There are
some bugs in that code, though. An updated driver is available from the 
Adaptec BBS and should be part of the forthcoming OS/2 bugfix release.

> master dma ? Perhaps the WD7000 ?

The WD7000 is also a bus master.

I have to think something else is awry here as I have been running 2
Telebit T1000 modems at 9600 baud for a year or so, without a single
character loss, and my dumb serial ports are not the 16550A.  My bus on
time is 7 and off time is 4.  I don't even use hardware flow-control and
the system is the news distributor (adaptex) as well.
You might take a look at the CLISTS and see if it is set high enough in
the kernel config parameters.  If you overflow the clists, you will lose
characters.  Just a suggestion.

I have a Micropolis 330 meg hard drive and need to choose a SCSI controller
to use it w/ my 386/40mhz.  Price is a major concern, and would like to know
what my options are for getting a fast, compatible card, hopefully for
under $200 and the cheaper the better. It would be nice if it supported
Linux, and OS/2 is a must.
