PS/2 Model 70 Not Booting From FDD

Hello,
I'm trying to get a PS/2 Model 70 up and running. It's an E61
model with the Hypertec CPU upgrade card providing a 486-33
processor. Problem is it won't boot.
When I turn it on it gives me the long beep, two short beeps
signal before going through the RAM test which doesn't throw
up any errors. Then I'm presented with the standard "161" and
"163" error codes to tell me that Lithium batteries are not an
infinite source of energy. Yet in the middle of these is the
error "2401" which I understand is to do with the Video
system.
The beep code also indicates a Video problem and a close look
at the IBM 90X8999 video chip revealed that a number of the
pins on one side looked to be corroding (not terribly
surprising considering the rust on the computer's case). On
the other hand I saw no issues with the text or the "read the
manual" picture displayed on my monitor.
Then I read this page:
http://ps-2.kev009.com/ohlandl/8570/8570_DX33_Upgrade.html
"If you hear ONE-long and TWO-short beeps when the computer
starts, then this is normal if there is an 8514/A adapter
installed."
Problem is I'm not using a 8514/A adapter, I'm using the
built-in video chipset. And even then it says nothing about
the "2401" error code (only shown due to the other errors?).
Anyhow, I would be happy to ignore these errors (which I'm
only mentioning in case they are related) if it weren't for my
inability to boot anything on this machine. I understand that
the Reference Disk must be used to set up the HDD for booting,
but having written V1.12 of this to a disk I can't get the
machine to even give it a try. The FDD flywheel spins and the
head moves back and forth once but this is nothing more than
when no disk is in the drive at all. I've also tried the home-
made DOS boot disk that came with the PS/2 and an original MS-
DOS 5 Double Density installation disk 1 with no better a
result.
As a slightly desperate attempt, I tried cleaning the inside
of the FDD and there sure was plenty of gunk. Yet it made no
difference. Also switch 6 on the CPU board DIP switch was set
to "off" while the default is "on" so I tried setting it back,
this also made no difference.
Finally I should point out that this is my first PS/2 so I
don't have any parts to test in this machine (nor much
knowledge to put into it either). Sorry if this post turned
out rather long.

If screen colors change 1. Display (any type)
0024 0100 / 0024 0200
If screen colors are OK 1. System Board
2. Display (any type)
Since the system will not boot to a refdisk, you can't run advanced
diagnostics.
http://ps-2.kev009.com/ohlandl/config/quick_system.html#Adv_Diags
And since the video won't change from white text on black background
while in POST, you can't be sure if the VGA controller is shot. Try a
different monitor if you have one. If the different monitor still throws
a 2401, then that pretty well narrows it down to the VGA controller.

The quickest fix would be for someone to send you a reformatted 60MB or
120MB DBA hard drive, with relevant System Partition created, then you could
sort out any configuration, diagnostic and other issues at your leisure.
That shouldn't cost a great deal.

to set up the HDD in the BIOS before it can be booted to? I'd
suspect the 60MB HDD in the machine already has an OS on it but
I don't know how I can use it (or even test it for that matter).

i am more than happy to provide you whatever you need (if i have it on hand

what you need to do is dismantle the system to bits, remove the battery, use
brush to soften the dirt, then use compressed ait to blast the dirt away,
pay attention to the sluts and contacts edges, use wipe alcohol (here in
Australia we know it as isopropyl Spirit) to clean contacts, inspect for
corrosion specially around contacts etc.., inspect for bludging capacitors.
use crt monitors, ps/2 do not like lcd screens.
reassemble, say the holly smoke prayers 3 times, "in the name of IBM, PS2,
and the holly smoke", at this stage you need to sacrifice the goat, turn it
on, if you see 16x error you're half way there.
next make sure the floppy is ok, they known for bad capacitors, sticky head,
the head metal cap protector tend to fall sometimes jamming the drive
mechanism.

same result. However the coloured "not OK read the manual"
picture always comes up all right. I also forgot to mention
that the BASIC prompt works, though a couple of times it has
frozen while I was typing a command, yet the cursor kept
blinking.
In any case, should a 2401 error stop the boot process? If so
does this mean I need an MCA video card to get around the
problem?

85nn series PS/2s didn't have the 'secret' System Partition as SCSI-based
ones and later, the IDE/SCSI-based 95nn series 56/57 and 76/77, at the
extreme end of the hard disk space, that is essentially a copy of the paired

Hi Computer Nerd Kev,
I have an IBM Model 70 here that works well, with the Hyptertec CPU upgrade thingy in it, and a spare floppy side mount board thing. Also have the various disk images but you can get those many places on the net. I haven't fired it for maybe about 12 months but I should still have a monitor around here some were I can use it with. I'd need to fire it up to remind myself what a Model 70 can and cant do.
If your near one of us, I'm happy to look at it, as well as strip and clean.
Moussa, you didn't see my small stash of MCA cards, or my box's of 86, 88, 80, 286, 386xx, 486xx and 586 CPU's, interposers, daughter boards etc or did you :)
I also have all sorts of RAM here, both chip and card (16, 32 etc pin, EDO etc)
I've kept a 50, 70, and a 77 plus a external brick 51/4" drive box.
And 2 wine box's of SCSI HD's, and another 2 wine box's of assorted IDE HD's plus some IBM ESDI drives. Also have 1 DEC Rainbow PC100A and a PC100B with color option and the DEC (Hitachi made) 241 monitors, miss my old PRO380.

adapter cables for both the card-edge and pin-connector 720KB and 1.44MB
floppy drives so that you could use "industry standard" 3.5-inch drives
in place of the "PS/2-specific" units that were no longer being
manufactured. I offered some up a while back, no one was interested, so
I tossed them along with several hundred pounds of old computer
equipment. I'm trying to eliminate my PS/2 and RS/6000 collections by
the end of this month, but other things keep slowing me down.

So there's a problem with the way "density select" is handled?
I would assume then that the signal goes high when a HD disk is
inserted while most drives would go low. However in this case an
inverter circuit could be used to fix the issue with relative
ease.

me as a PS/2 newbie, it seems strange that a GPU error would be
preventing this. So I'm not too sure a replacement video card
would fix the problem...

486 in the Hypertec card with a similar one in an old laptop I
have.
When I took the CPU out of the Hypertec card I discovered
about four of the pins are very badly corroded at their bases.
To check what I saw wasn't just a coating on top, I went to
try lightly scraping at the base with a small screwdriver but
the whole pin moved with pretty much no resistance just when I
touched it. So I think this processor may be at the point of
no return.
The laptop had a 486SX-33 CPU and I (perhaps foolishly) gave
it a go in the PS/2 even though the Hypertec card is meant for
a 486DX-33. The result was error code "103", "Timer Interrupt
Failure".
Tomorrow I'll try to find some more suitable 486s to try.

that's a bomber, well you need to speak up soon, most of the stuff i have
is heading to the dumpster soon if no one would take on the challenge, i am

machines to grief on, most likely a 8565, and a 8595/9590, i have already
started with the clones and i am half way through already, so 6 months then
PS2 stuff.
half of the machines i have were all cleaned and reassembled but that was
like 15 years ago, most of it now sits in the shed is humid and roaches and
mice heaven.
from memory i sent most of my replay boards to Basil, i might still have

so will have to spread the 640x480 or 1,024x768 over an LCD that can
handle 1440x780 or so.
Never tried to use an 8514/A at 43 hz interlaced, that might not synch.
LCDs want non-interlaced and 60Hz minimum.
I have a 19" ViewSonic that makes 800x600 look good.

underclocked on the machine (advice gladly accepted). The one

Well I tried one of the new CPUs and although I likely now have
the fastest PS/2 Model 70 on the block (actually I probably had
that title before as well), it still behaves exactly the same.
Same error messages, same lack of any attempt to boot from the
FDD.
I suppose that narrows down the problem to some small extent, if
nothing else.

of coating on top that looked as if it had dripped or leaked
from somewhere. I cleaned it off and the chip looked fine. As
the machine isn't throwing up a specific floppy controller
error, I haven't given the thing much thought. I suppose no-
one knows any details technical enough to diagnose the chip
with an oscilloscope? Yeah, optimistic I know.
Mind you if the controller were dead, I'd then have to find
another dead PS/2 to grab a fresh chip from.

Ah right. I guess my attitude towards finding information
regarding chips on old computers has become rather defeatist, I
didn't even bother to look for a datasheet. The chip on the Type
1 planar in my Model 70 is a NEC "72065L".
The datasheet here,
http://www.ic-on-line.cn/view_download.php?id=1094399&file=0042
\upd72065_305968.pdf
gives a fair bit of information so I might have a go testing
some of its outputs when I get the chance.
Thank's for pointing me this way Moussa.

didn't even bother to look for a datasheet. The chip on the Type
1 planar in my Model 70 is a NEC "72065L".
The datasheet here,

\upd72065_305968.pdf
gives a fair bit of information so I might have a go testing
some of its outputs when I get the chance.

IIRC, the problem with this machine was a specific VGA error on POST.
A graphics adapter, like an XGA-2, might be the workaround by overriding
the planar VGA, and hopefully also the error, to let the machine proceeed.
The system configuration is entered, so the recommendation, in "slow" mode,
which disables caching. I have Kingston's Blue Lightning 486/BL66 working
in my Mod. 70 and could so far start sysconfig in the usual "fast" mode, but
I
have also an XGA-2 and a SCSI controller working there.
