IBM PS2 16X Series Error Codes: 162, 163,165

Last modified:

These errors signify that the machine did not recognize its configuration on powering-up.

If you have installed any new equipment (or REMOVED any devices) you will certainly have to run the REFERENCE or STARTUP disk for your particular model. The ISA PS2s (models 25, 30, and 30/286) use a STARTUP disk. The MCA systems (50 on up) use a REFERENCE disk. If you don't have this disk, a compressed file can be obtained from the IBM Web Site Files Download area.

A complete listing of the IBM REFERENCE and STARTUP disks for PS2 (complete with Links) is provided in the table at the end of this document.

Files with exe or com extensions are self-extracting.

IBM sometimes archives its files with dsk or tg0 extensions. These files are restored using the bluespecific programs LOADDSKF.EXE, for the dsk files, and TGCONFIG.EXE, for the tg0 files. Just to complicate matters one step further, you obtain LOADDSKF.EXE by downloading a self-expanding program, LDF.COM, from the IBM site. In the same manner, to get TGCONFIG.EXE, you need to download TGSFX.COM -- also called teleget.

Follow this path. You download LDF.COM for dsk files or TGSFX.COM for tg0 files, the STARTUP, and any OPTION files that you might need. You run LDF.COM to yield LOADDSKF.EXE. You then run LOADDSKF filename.dsk to finally get your REFERENCE or STARTUP disk. With the tg0 files, you'll run TGSFX.COM to derive TGCONFIG.EXE. You then execute TGCONFIG filename.tg0.Most of the OPTION files, just to be cantankerous, are self-expanding, producing a number of ADF files. The REFERENCE or STARTUP disk is used with the ADF to define optional devices.

You may also need an additional configuration disk from the manufacturer of the MCA, but non-IBM, hardware options. The MICROCHANNEL ENTHUSIAST's PAGE has a great library of ADF files.

If no hardware changes have recently been made, turn the system back off. Make sure that any cables or power cords to external hardware (5.25" disk drives, external hard drives, or other external storage) are properly connected. Turn your system back on. If you are still getting the 160 series error codes you will have to boot from the STARTUPor REFERENCE disk for your PS2. Run AUTOMATIC CONFIGURATION. You may also have to run SET TIME AND DATE from the STARTUP disk menu.

If after the machine has been off for a half and hour or so and you again get the 160 series error, hit F1 to try to boot. If the machine fails to boot, the hard drive might have become unrecognizable from a virus, other source of file corruption, or hardware failure. Address the software issues first. Try booting from a regular boot floppy.

If the hard drive fails to boot and/or simply goes to BASIC, then read NO ROM BASIC.

If the system fails to boot from the original reference disk again see if the system will boot from a known good boot disk. If it does, then your reference disk is defective. Follow the directions above and make another copy. If the system will not boot from a known good boot disk, then the floppy drive is the trouble. Try a cleaning disk on the drive. A cleaning disk is available from any large computer or office supply. Cleaning disks work just like cassette or VCR head cleaners. If cleaning does not help, then the drive itself probably needs to be replaced. PS2 floppy drives are system-specific (non-standard) and very expensive to buy new. In most cases, it's only worth replacing them if you can find one on the cheap at a computer show, USENET, or, best of all, on a scrapped system in the garbage!

CMOS Battery In A PS2 Model 50. Be Careful With The Plastic Clips. It's Easy To Break Them!
Quite possibly the internal battery needs to be replaced. This is located in a holder on the side of the case, above and away from the motherboard (in all models except the 55SX). Tension is maintained on the battery by a plastic clip. TREAT THIS CLIP GENTLY. YOU'RE SCREWED IF YOU BREAK IT! Make sure that the power is off when you remove the dead battery.

After replacing the battery, you will have to run the IBM STARTUP or REFERENCE disk and any special option configuration disks.

For the 55SX the battery is contained in a large IC (manufactured by DALLAS) that is inserted into the motherboard. With the power off, and yourself grounded, carefully pry out the old chip from its socket and insert the replacement.

Sometimes, since the CMOS is intergrated with the battery in this model, it is necessary to clear the CMOS before the STARTUP program can properly configure the system. To erase all the values from the CMOS use the DOS DEBUG routine. From the DEBUG prompt type in the following series of commands:
o-70-13 (enter)
q (enter)
This will clear the CMOS. Turn off the machine and now boot from the REFERENCE disk.

Some PS2s (all model 60s, in my experience) are just absent minded and tend to lose their configuration for no discernible reason. Just keep the STARTUP disk handy. Peter Wendt suggests that this problem in the PS2 60 and the model 80 is due to the power supply becoming congested with dust. He says that blowing the power supply out with air will solve the problem. He also advises that this procedure will produce a large cloud of dust!

The REFERENCE disk for the PS2 8533 (a 386SX notebook) is called 8533r12m.exe or 8533r16m.exe, depending on the clock speed.

Hint: Most of the REFERENCE files start with the letters rf.

Many more files can be found at The IBM FTP Mirror Of The PCC BBC

Warning! If you're too lazy to look up the files that you need, DO NOT ask me to do it for you -- unless it's part of a (lucrative) offer of full-time employment!
