PS/2 E (Model 9533) FAQ
Don Hills posted the original PS/2 E (Model 9533) FAQ on CompuServe to the PS/2 Forum. His work provided the base for my adventures with the "Big e".
The PS/2 E (model 9533) system unit has a PS/2 model 35 motherboard.
486SLC2 25/50 MHZ CPU, 4 MB memory soldered in, 2 sockets for IBM PS/2
style SIMMs (2, 4 or 8 MB), to a maximum of 16 MB. IDE disk drive,
only enough room inside for a laptop 2.5 inch IDE drive. XGA-2 video
on motherboard. One ISA bus slot, depending on the model it may contain:
See: the 486SLC2 processor in the 33 is *technically* a souped-up 386SX. It is an interesting mix of technologies.
- the external bus is from the 80286: 16 data and 24 address lines
- the internal 16K Level-1 cache is inherited from the 386SLC
- the 32-bit processor core is compatible with a 486SX (no MathCo integrated)
- the power-management comes from the 386SL laptop processor
- the pin-out and case (PLCC) comes from the 386SX
- the additional MathCo is a 387SX-25
- the internal clock-doubling is taken from the 486DX2 line
16MB RAM Limit
387 Math Coprocessor
HARD DISK DRIVES: It'll accept any 2.5 inch IDE laptop drive, provided it is not too "high" (thick), as it has to fit under the diskette drive. I think the drives come in 2 common heights- 12 mm and 17 mm- and the space available is only about 15 mm high.
Disk Manager for
HD Cable 39G6566
has the right power tap-off. Laptop IDE drives have the power wires on
the same plug as the signal cable, but the 9533 is "desktop" IDE where
the power is separate. The IBM cable splits out the power wires to
a special connector from the power supply.
The BIOS DOES have support for the 2.88MB floppy. IBM Thinkpad 720 diskette drive. The 1.44MB floppy is a Teac FD-05HG-263-U or IBM Part 1619640.
Note: I had a strange problem with
my floppy. Tried reseating the tape, no go. I was turning it over, looking
for model numbers, when I heard something rattle. Turns out somebody had
stuck a safety pin in the floppy. So if small children have been in the
area, just remember they like to stick small objects in anything with a
door. VCRs. Tape decks, Sewing Machines. Computers....
BUS: The machine has a single ISA slot.
From Don Hills
I installed a Sound Blaster 16-SCSI adapter. The CDROM drive cable ran out of the back of the case to the drive, which I put in an external box with its own power supply. It sits on top of the PS/2 E. Note that the internal power supply in the PS/2 E is 24 Watts. I had to disable the internal speaker amplifiers on the sound card, it was hanging the machine when loud sounds were played. I now use external amplified speakers. Most recent sound cards no longer have internal amplifiers anyway- people prefer external amplifiers to get more power, and control over volume/bass/treble etc.
DISPLAY ADAPTER: The on-board display adapter is an XGA-2, for DOS/Windows you will need the XGA device driver diskette (latest version is V2.12.)
>Yes - but the XGA-2 driver with Winblowz is for the MCA-version only. The 9533 has ISA XGA-2 and it seems it does not work very well together. I'd managed toget it going under Win95 IIRC ... I deleted the Wincrap from it and installed Linux ...
From Don Hills (looks to be a long thread)
As for hard disk noise, the APM for DOS and OS/2 works fine.
VESA POWER MANAGEMENT
When connected to a suitable system
unit, the display can operate down to step 4.
DIAGNOSTIC AND SETUP DISKETTES: It is an ISA bus system and, in common with IBM's other PS/2 ISA bus systems, does not have a Reference diskette. It does have a "Starter" diskette, an image of which is in the library here. There's also a "Utility" diskette which contains, amongst other things, management utilities and drivers for the 4-slot PCMCIA adapter that some models shipped with.

PCMCIA Device Drivers for 9533
Win95 PCMCIA Support
The default choice of I/O 03E0-03E1, IRQ works. Windows will also instal Socket Services automatically.You do not need any DOS drivers whatsoever.
IF the device you are using is visible under Explorer, but comes up as not ready when you click on it, try reformatting it. This was one of my problems. I could see the PC hard drive, used it to transfer W95 setup files, but it would not respond to Exploiter. Until I reformatted it.
The PCMCIA adapter acts as a bus from the system board to the option adapters.
If the computer has a problem, carefully remove and reseat the riser card, any PC Cards, and the PCMCIA adapter. If, after reseating these boards, you get an 80XX error code, replace the PCMCIA adapter. For any other symptom, continue with the steps below.
If you suspect a problem with the PCMCIA adapter, do the following.
If the PCMCIA adapter diagnostic tests find no problem, suspect a PC
Card option adapter connected to the PCMCIA adapter. To test the PC Card:
Editor's Note: And just trot right over to your local IBM rep, and he (or she) will be glad to sell you one for $500+.
Note: Before you replace a PC Card, be sure its application software and any required drivers are installed correctly on the computer.
I have disconnected both solenoid headers on my e and have no
problems under Win95.
NT 3.51 on the Big "e"
I thought this was a twisted joke.
Well, it was not tricky, really. Rather than attach a CD-ROM drive (couldn't figure an easy way of doing that), I simply copied the NT i386 directory to the hard drive, and installed from there - I chose to use a 105MB PCMCIA drive as a big diskette, and created a suitable DOS boot disk. I've swapped the hard drive for a 512MB one, so space is not an issue. I'm using the normal 4-port PCMCIA adapter, but haven't checked (as far as I recall) if all four ports are available. I'd suspect only two ports are recognised.
I've just tried shoving a couple of PCMCIA devices into it, and of course
the damn security clips are activated, so I can't. Arse. I haven't had
any luck running the DOS or Windows lock Programs under NT. I can't
even get the DOS one to run under DOS! at the moment it's only
Um, NT 3.51 isn't exactly nippy, but it serves well as a network device.
> are you implying that you are using a pcmcia adapter under 3.51? Do tell...
Nothing to tell - it saw it, and installed the drivers - the PCMCIA
device is started, basically. I'm not sure how to check whether it's running
as two instances of a two-port driver, or one instance of a four-port driver,
and I can't get any extra cards into it at the moment. I have to say, I
get so bloody frustrated with the 4-port card locking the cards away, I
have seriously considered slinging the card and just making do with an
ISA Digital 2-port 82365sl that I have spare. When I
To be honest, the trickiest bit is remembering that when I apply SP5 to it, it overwrites the t-r adapter driver with a duff old version, so I lose my remote control. Obviously the punishment of having to get a monitor cabled up near it is enough for me to remember that for a week or so... then I forget and do it all again - Doh!
> I suppose I could try 4.0 on my e. As it uses the i82365SL pcmcia chipset, it might work.
Yup - it will. I recall that NT 4 was using around 24MB with me logged on, and without much configured in the way of services. Thrash! I tried NT 3.51 with the Shell Update - a sort of 3.51/4.0 hybrid, but that Explorer shell ate up the RAM, and only shaved 2MB off the NT 4 memory usage. Still thrashy.
I'll give you any assistance I can with NT on this box. My recollections of the installation are a little hazy, as that was about four months ago, so apologies if any of this is annoyingly vague. The box just runs and runs - it's been rebooted only to move house, and again whenever I pull the wrong power cord. I haven't got it to boot without the keyboard present, so I just leave the space saver plugged in and tucked out of the way.
I suppose I ought to carry on the quest, and get it sorted out. I'll need to shrink the partition to make way for a Win3.1 area, so I can boot that and eject my cards without using a screwdriver. Cleaner, but not ideal.
I did have OS/2 4.0 on it for a while - got really narked trying to
install LanServer 5 onto it - whatever I did, it refused to play ball unless
it could see the CD. Hmm. The PCMCIA adapter support was a dream, though!
Opening the 9533
Hopefully, it's unlocked. Who has a key? Open the front cover. See the white latch in the center? (under the black cover latch). Pull up on the white catch while pushing it back (latch is mounted to the frame). Push forward on the case while pushing back on the latch.
Do NOT try to pry the case open at the back! You do NOT need any tools to open the case!
Power supply / floppy / hard drive mount Removal
Look at the rear of the case. There is one standard screw to the upper left of the power socket. Unscrew it. Now you can lift the front of the mount up and pull the entire mount up AFTER you unplug the cables!
First, disconnect the floppy tape connector. Look here
Tip the front of the mount, then pull the HD cable out of the planar.
Look at the left side of the mount. All sorts of cables, eh? The main power leads go into a black connector. Notice it has tabs at each end. Squeeze those tabs inward while pulling the entire connector up. May have to wiggle it some. Also, pulling the mount towards the left side gives you more room to grab the power cables....
Next, there is a white power connector to the left. I just grabbed the wires and pulled straight up. Crude, but it works.
