You may like their hardware, but I have found them to be totally UNresponsive
if you ask them to resolve a problem. In fact, I had to call them 6-7 times
because they never return phonecalls and the problem was never resolved
anyway, so I gave up.

I fact I am lodging a complaint against their distributor Mini-Micro and
Bustek with Better Business Bur.

By the way if any of have a problem with Bustek, the company president
is Jessie Chen. Drop him a letter with CC: going PC-Week Editor or such.

Rotating Memories will sell an IBM 3.5 drive (1.004 Gig formatted) for $1750.
They will first try to sell it at a higher price, if you stand your ground
and tell them others have bought it at $1750 they will relent. The
Tel. number is (916)939-7500 ask for Marry Harrison, do not talk to other
sales people, they cannot make any decisions. Note: I am not sure about their
delivery, I ordered the drive a week ago - still do not have it. Problems:
they have tested it with very few SCSI controllers, only three work for
sure: UltraStor, DTC, FUtureDomain. Adaptec DOES NOT work and therefore
Bustek probably does not work either.
Alternative: buy from Argo computers a Fuijitsu drive for $1777.

In general I have had good results with the Bustek 742 in that it worked
in '1542' compatibility mode.  Be aware that the Bustek 742 and Adaptec
1742 use different programming interfaces in full 32-bit EISA modes.
Thus if you really want the full power of this board, you must use a 
Bustek specific driver.  If you are using it under DOS using the built-in
ROM as the driver, you'll be OK.  If you need a device driver for DOS
for whatever reason, I think Bustek has one.  I do NOT think that there
are EISA mode drivers for this board for any Unix or Novell OS yet.
You should check with the factory directly as I know they are actively
working on them as we speak.  From a support/reliability standpoint,
I like the boards and company very much.  The factory phone # is
408-492-9090.  I am not affiliated in any way with this company.

I just got some brochures from Corel. Called them about a month ago for
info. If your interest is in OS/2 especially v2.0, buy the Adaptec. v2.0
has built-in support for the 1542B as well as a couple of other Adaptec
controllers. 

When installing, OS/2 detects the type of controller you have and installs
the proper drivers. 

One more important fact is that using the 1542B with OS/2 v2.0 gives you
HPFS which is better than FAT. Currently, Corel's support for OS/2 is
limted to FAT.

I'm running OS/2 2.0 right now with a 1542B, Maxtor LXT213SY formatted
for HPFS, 3.5 & 5.25 HD FDD and a Toshiba 3201B CD-ROM. It works great!

Price-wise, you should be able to obtain the 1542B (controller only) for
about $160 or so. The kit which includes drivers for DOS, OS/2 and
Netware costs about $305.

2. edit SCSI1.U to change SCSICNTL.EXE.Z to SCSICNTL.EXZ
3. run QUUDCD.EXE (version 2.4) on SCSI1.U, that reads in also SCSI2.U and
    produces SCSICNTL.EXZ,
4. run UNCOMPRESS.EXE (no version, dated 12-15-87) with -I (image mode) on

This may rank as a Frequently Asked Question, but I haven't seen the answer.

All the SCSI buses that I have seen are internally terminated.  This makes
it a pain to add devices to the bus, since it is necessary to open the case
of the last device in line.  Newer SUN equipment (for instance) seems to have
external terminators.

Can any SCSI bus be externally terminated?  How does one go about doing it?

Thanks,
Greg

I had a similar problem with an SCSI driver for a unix on 386. The solution
was to edit /unix with emacs and take one entry that you don't need and 
write in the string that the inquiry command on the new device returns. You 
better be very careful if you try this. Don't forget to take a copy of

Problem: I have an ISA intelligent hard-disk controller (made by
PSI Dallas)and I love it since it brings me the joy of .4 ms access
time on a 600MB hard disk, nice data transfer,etc. I run my ISA
motherboard at 16Mhz bus speed and use quality add-ons that won't
blow up (the PSI takes it nicely).
Now: I want an EISA board, and I still want to use my ISA controller,
since PSI does not have an EISA version yet and DTP just withdrew
theirs from the market  ( I do not like Mylex). Trouble is, the back-
ward compatibility of EISA with ISA is of sych a nature that you can 
only run an ISA bus at 8Mhz on an EISA motherboard!!
Question: is there a way to write a driver that will go around this
problem (i.e. avoid the slowdown of the contoller talking to the
BIOS on an 8Mhz bus?)..

Ummm, one other little problem. The host adapters on both Sun's will be

The 1542 supports some SCSI-II commands, whatever this means, but it can surely
not do Fast-SCSI-II.
The 2624SA does work with CCS (SCSI-I) with an 1542 and with SCSI-II with an
1740. I have both configs working. My recommendation is, if you plan to buy
a 1740, to get a 2624FA that can do Fast-SCSI-II. Some Fujitsu guy spoke about
transfer rates in the 8Meg range. This should be buffer to PC-RAM, but very   
impressive anyhow.

I wasn't able to find a difference using a 1542, a 2624SA and MS-DOS.

One point here - evidently the current version (2.0) that is shipping
this month has support for Adaptec boards built in.  IBM and Adaptec
(jointly) produced the drivers so you will *NOT* need to get any
special drivers in order to run OS/2. 

Reports indicate that the installation program recognizes the adapter
and no special work is is needed to "work around" anything.

There exists an enhancement to the DDS tape format standard called
"DDS DC" which specifies format enhancements for writing compressed
data to tape.

Both HP and Archive drives adhere to this standard, making interchange
of "compressed" tapes possible.

I am not sure what WangDAT's current position is on this. They did
release a drive with what they called "group compression" which
does not comply with DDS DC (not only will an Archive or HP drive be
unable to decompress its data, but it is not even possible for an
alternative drive to read the data uncompressed such that it can
be decoded in the host).
I believe WangDAT might be going to or have released a product based on
DDS-DC.

The algorithm used in DDS-DC is a modified form of Lempel-Ziff.
The IC used in both the HP and Archive drives was developed by HP.

The method of controlling compression enable/disable and configuring
other aspects of compression via SCSI has been standardised in the
SCSI committee such that host drivers wishing to "gain control" over
what the drive does don't have to be customised for different vendor's
drives.

The kernel will boot, find and mount sd6.

I'm sure it all makes sense to those who wrote the various programs. :-)

Actually, it does make some sense.  The boot prom deals with physical
(vs. logical) devices, and it uses hex, so 0x18 == 24 == scsi#3 * 8
(# luns per target).  The tape program uses logical device names, and
for some reason Sun chose to map like:

	name	addr
	sd0	3
	sd1	2
	sd2	1
	sd3	0
	st0	4
	st1	5
	sr0	6

I *think* SunOS treats the disk as sd6 because it can only support two
luns per target, so scsi#3 * 2 == sd6.

BTW, I've also configured a (4.0.3) kernel with the disk at scsi#0,
boot as sd(0,0,0)vmunix, and SunOS mounts as sd0.  However, if I didn't
have BOTH sd0 AND sd6 config'd in, the system wouldn't boot.

I do not speak for IBM, and vice versa.  We like it that way.

The schematic you posted for drive connection is perfectly acceptable.
I use it all of the time.  You must do the following to properly terminate
this setup:
1.  Remove the terminators from the SCSI host adapter.
2.  Make sure the hard disc AND tape drive are each terminated.
    These can either be internal (on the PC board of the unit), or
    external, resistor units which plug onto a cable connection.
I have the Future Domain 25 pin connector diagram floating around
somewhere, but not where I am now.  I'll post it in a reply to this.
