I am getting an error message when I boot up a recently donated PCs Limited
XT clone. The error is
ARC Turbo Board
X Turbo System Error # 04
Does anyone have one of these boards, I believe the error means the board
has been removed, and the system can't find it/bad board. If so, please
advise the $$.
I don't think the board is specific to PCs Limted, I found a general manual
called "Turbo-XT Main Board" that seems to be the OEM of the PCs
Limited-branded motherboard. I assume there is a separate daughterboard
the the "Turbo" part. Yes?
Thanks

Open it up and take a look. Maybe the daughterboard it there and just needs reseating.

I used to use (and service) PC Limited stuff back in the 90's at Macro.
I don't remember a turbo board, just a normal XT system board. Pop the
case open and check.
If I recall PC Limited and Dell (what they became) came with call in
service from Xerox. Maybe give them a call? ;-)

Obviously I opened the box. So Inguess the Turbo board is just
"motherboard"

Or it was removed and the config wasn’t updated.

Back in those days I made my living assembling and repairing those XT machines.
The motherboards were almost universally from a handful of manufacturers and generally
referred to as "Turbo Motherboard XT."
I never saw any type of daughterboard. Generally they had a switch that selected
"normal" (4.77 mhz) or "turbo" (8 or 10 or rarely 12 mhz.)
Is this message you are getting a bios message or is it from dos trying to load? If it is
bios, it is something I have never seen. If it is from dos, it should be easy to get
around it. The bios on almost all of them was either ERSO, Award, or Phoenix.
But my memory is starting to fade after 35 years.

What cards are plugged into the motherboard?
What video do you have connected?
On 3 digit error codes, 4xx was monochrome video problems
Do you get any beeps?
Does it have a dipswitch (SW1)? What are the current settings of it?
With all cards removed, and SW1 (if it has one) switches 5 and 6 off, do
you get beeps?
Do you have any other 5160s available? (consider swapping BIOS ROM)
4:16 p.m.
Guys...I just wanted to know if anyone has either an original user/tech
guide or worked with the actual specific machine. Maybe there is a
password reset util disk image floating around specific to the original PCs
Limited system, or a backdoor password ...that's what I am after...the
original stuff that came with it.
I learned ctrl+alt+ - toggles Turbo/ regular mode, by trial and error.

Sitting here paging in old stuff from my brain. I'll bet you have an
ArcNet card, and on the card it has a BIOS bootloader that was designed
to do a BOOTP load of a DOS from a Netware or 3Com server.
Pull the card and it will probably boot normally off the floppy.

BOOTP load of a DOS from a Netware or 3Com server.
Could that be RPL? I have a WD800x ethernet card with netboot PROM sold
with a "Netware ready" or some such workstation that it took me a bit to
figure out was looking for an RPL boot server, not BOOTP/TFTP.

I didn't get all of the replies, until a thread already developed (below)
with responses already embedded.
I don't think there actually is a diagnostics disk or manual, this PCS
Limited is ancient, before the corporate
structure of the company was established. There are other Turbo XT
motherboards that are almost right
but no PCs LIMITED-specific documentation is a match to the motherboard.
So, I just went forward and set up the PC working with what info I could
find. I am more experienced with XT
type IBM and clone systems than probably anything else, I think that PCs
LIMITED box I have is just a
generic clone with no frills, cheap XT clone. If it wasn't PCs Limited I'd
probably not spend so much time
on it.

That was it, Remote Program Load. Simple protocol, ran at the MAC layer
if I recall, and worked. However it had an issue with routers and I
think BOOTP was easier to use with a "helper" on the switch or router to
handle it.
Old stuff. But yes pull that ROM chip or Arcnet card and it should boot
to floppy or HD.

It boots fine, did I say it did not boot? I don't remember. There is no

You did not say it did not boot, but it was implied by saying that you got
an error message when booting.
Many of us misinterpreted that to mean an error message with unsuccessful
boot, and asked questions about the configuration, and attempted to give
some suggestions of things to try.
Sorry for the misunderstanding.
Still don't understand the questions about password reset/backdoor; 5160s
do not generally have a password, and some folk conflated that question
with CMOS (sometimes password protected) on 5170.

Well, I appreciate that people answered my question. I sometimes ask

I think that the tubo mode is not happening, it's running like a regular
XT. I have seen it go into Turbo mode once or twice, so there is a
marginal chip somewhere that needs to be replaced. That's my final
decision.
Either way, I have filled the hard drive up with various software from the
time period and put it out for people to use in the museum. If you're in
the south-eastern PA area, feel free to stop by and check it out.
The PC Limited machine from the VCForum I think is the same one as this
one. I think the guy gave up on it and donated to the museum. It needed a
new power supply, hard drive controller, disk drive to get it running
again. I put MS DOS, removed the botched IBM DOS someone had attempted to
load.
Really, you're right. It's just a cheap clone, but it's a cheap clone that
happens to be one of the first PCs made by what would become Dell Computer,
worth saving and keeping running!

Interesting thought. I don't think I ever had to look for a layer 3 RPL
helper. RPL seems to have fallen out of favor around the time IP took over
the world.
