In the Uniprint file there is/are one or more color model statements,
something to the tune of a CMYK, and there may well be another one
telling which dithering algorithm to use. (You can tell I don't have
the stuff available right now.)
There's also a B&W version of the 800 available, so this calls for
examining its Uniprint file and comparing it to the file for the
ESC 800. The answer may become obvious. Right now my computing time
is getting soaked up getting the new motherboard and reinstallations
snuggled in.

Ryan,
The easiest modems to install are the external ones. YOu just plug the
cables in and you are set to go.

I move a lot of AOpen AX6BC's, IMO an excellent value and with
jumperless setup. BTW you can get a P-II/400 for just a few bucks
more than the 350.
Also the PGA-style Celeron 466 is cheaper than a P-II/350 but the
motherboards seem to be oriented more towards desktop use (integrated
video, sound, etc.). Slot 1 Celerons are disappearing.
In the Super 7 department, the K6-3's have come down in price and
are really zippy. The FIC VA503+ mobo (1M cache) is a nice fit for
this, and it's easy to find a mini-tower case for its BAT form factor.
If I were you I'd look at this first.

Subject: System hangs with dual SCSI controllers (Tekram DC390)
Date: Fri, 23 Jul 1999 14:27:54 GMT
Hi
I am having severe trouble with a dual SCSI controller configuration on my Linux box -
PCI/VLB ... not very modern hardware though ;-)
I would appreciate any hint that would help me solve the issue and bring my second
DC390
to work with its lonely friend in slot one.
Martin
(Deutsche Kurzfassung am Ende der Message, falls mein Englisch nicht klar genug ist
:-))
I configured a RAID-5 md device out of six 1GB SCSI disks. First i let it run with two
disks attached to an Adaptec 1542 and four disks attached to my DC390 (the plain
vanilla
version using the tmscsim driver). I chose this setup because i had used the disks
connected in this way before and I had only one internal SCSI cable with more than
three
connectors.
Common sense and knowledgeable people recommend using identical controllers wit the
same
(small) number of disks attached, so I decided to buy a suitable cable and to install a
second DC390.
With this new setup everything seemed to be fine first: ckraid's, and e2fsck's ran
without
a glitch and I even looked at some of my files from my wintel-box ... Samba is a fine
piece of software, isn't it ?
Soon I noticed a problem - under heavier load my Linux box committed suicide - just
hanging with the activity LED's of both DC390's and two disks active. I had to do a
hard
reset, ckraid, e2fsck ... and could crash my system again. I am now using the six disks
attached zo a single DC390 and everything works - but remarkably slower than before
with
two of them on the Adaptec.
So, for short:
Symptom: system hanging, no reaction on any key (except power and reset that is :-)) )
Configuration:
- ASUS PVI486SP3 PCI/VLB/ISA motherboard
- Intel PODP5V83 Pentium Overdrive 83MHz
- 24MB of FPM RAM
- Award BIOS 4.50G with default settings
- ADAPTEC 1542B ISA SCSI controller with 5 CD-drives attached
- two Tekram DC390(T) Rev. 2.02 PCI SCSI controllers with one Seagate and two Compaq
drives on each
- VLB VGA card stealth64
- ISA ISDN card Teles PnP
- ISA ethernet controller NE2000 (genuine Novell)
- 3 IDE hard disks
Action taken so far to resolve the problem:
- exchanged the tmscsim of SuSE6.1 (2.0d) with Version 2.0d20 sources from
http://www.garloff.de/kurt/linux/dc390/dc390-20d20.tar.gz and recompiled the kernel
(SCSI
support and both aha1542 and tmscsim compiled in)
- disabled disconnect for all SCSI hard Disks ( this delayed the crash a tiny little
bit )
near the end of this post (before the few german lines) you can take a look at parts
of my
boot messages and some peeks into the /proc tree.
*just for the curious*
a bit of History:
I had a configuration with 5 SCSI-Disks and 2 IDE Disks, booting form /dev/sda1 (sda
was
on an Adaptec 1542 with BIOS enabled and sdb on a DC390), I had configured two RAID5-
md's
the first consisting of the whole smallest IDE disk and equally sized partitions on the
other IDE and one SCSI hd on the Adaptec and one on the DC390. My root and /usr
filesystems were on the remaining partitions on the SCSI disks and the swap file on the
remainder of my second IDE hd.
*** never do this sort of setup, you have been warned ***, I paid my price by hours of
work to recover from a double fault. The swap disk failed and left me with a hanging
system and after power off the RAID array was not suitable for degraded operation
because
it did not only miss a disk but was inconstent at the same time.
Normally, degraded operation (one disk missing) works fine and recovering from a system
crash with ckraid just works, but the combination of these faults is horror, so never
share a disk in a RAID array with a system critical file system on another partition on
it.
The remaining three disks formed a second RAID-5 md (one disk on the Adaptec and two on
the DC390)
-- before the mixed IDE/SCSI array lost it's second disk I noticed that it was
considerably slower than the array of three SCSI disks, so I decided to rearrange my
setup
to IDE for the root fs and the swap drives and just one fast SCSI RAID-5. I backed up
both
RAID's to CD's, attached SCSI disk numer six as number four on the DC390.
This setup worked well but I thought it could be faster if all six disks would be
driven
by a modern PCI controller (the maximum transfer rate of the 1542 is 5MB/s). Faster it
is
- but it locks up the system :-(( I can tell that it must be faster because a ckraid
runs
as fast with the 6 disks as before with one on the 1542 and two on the DC390)

***************** german abstract ... deutsche Kurzfassung *************
Sechs 1GB SCSI-Disks sind als Software-RAID-5 /dev/md0 konfiguriert.
Aus historischen Gruenden waren es urspruenglich zwei an einem Adaptec 1542B und vier
an
einem Tekram DC390(T) Rev. 2.02
Leute, die es wissen muessen, und gesunder Menschenverstand sagen uebereinstimmend,
dass
die beste Konfiguration aus identischen Controllern mit einer gleichen (kleinen) Zahl
von
Platten bestehen muesste.
Das waeren dann also zwei DC390 mit je drei Platten. Diese Konfiguration fuehrt bei
hoeherer Last (allerdings nur von einer Workstation ueber 10Mbit Ethernet, also wohl
weit
weg vom Grenzbereich) zu einem absoluten Haenger des Linux-Servers - ausser dem
Resettaster und dem Netzschalter geht nichts mehr.
Dabei leuchten die Aktivitaets-LED's an beiden Controllern und je einer ihrer HD's.
Die Konfiguration meines Systems steht oben (ist auf Deutsch bestimmt nicht
verstaendlicher als auf Englisch)
ich habe bereits den Originaltreiber von SuSE6.1 (tmscsim V 2.0d) durch die Version
2.0d20
( http://www.garloff.de/kurt/linux/dc390/dc390-20d20.tar.gz ) ersetzt.
In der Doku zum Treiber raet Kurt Garloff bei Problemen den Disconnect fuer die
Festplatten auszuschalten - das habe ich getan und damit das Auftreten des Fehlers
etwas
verzoegern koennen ... geloest ist das Problem damit leider noch nicht und ich weiss
nicht
mehr wo weitersuchen :-(
ich danke jedem, der diesen Roman gelesen hat fuer seine Geduld ;-) ... und wuerde
mich
ueber Hinweise "die zur Ermittlung des Taeters fueheren" freuen.

We all do. :-)

You bet. External is the way to go for RAID. Now keep in mind there is
no SCSI per say, but SCSI 1, SCSI 2, SCSI 3, Wide SCSI, Ultra Wide SCSI,
Differential SCSI, and LVD SCSI. There is some clue with the number of
pins, but check to be sure. SCSI 1-3 will support up to 8 devices including
the controller. Wide and up will support up to 16 devices including the
controller. There can be more than one controller on a bus! <This is how
Storage Area Networks work> With 15 drives, you NEED an external case.
|If so:
|How long can the cable be?
It is 15 feet from end to end, and if you have both internal and
external, they are both included. Of course Differential SCSI was created
to make this longer, and LVD does as well... <sigh>
|There's one cable connection, so, I take it the drives are chained
|together or does the cable split off?
Each just daises, like IDE. The limit is addressing, like IDE. It is
just a higher limit.
|Is there perofrmance loss for using external drives, like radio
|interference on the cables?
Only if you use cheap cables. The good stuff is shielded. But then
again, read my sig... :-)

Well, Sun Microsystems makes some awesome quad CPU motherboards. :)
But you probably meant x86 compatable, right? Where you looking for
PPro, or Xeon, or something using a specialized chipset for the Pentium
processors, or what?
