Need help with an ancient PC Vectra QS/20

I am getting a POST code of 1102 every time my QS/20 boots up

I searched this code and it means: Timer 2 failed to register test.

After code ram gets tested (4 MEGS) and proceeds to boot normally and reaches DOS.

I ran the setup disk and there is no problem.

Could anyone help me with this error code. I still intend to use this computer, but am unsure what this code speicifically means? Is there a malfunction, is it critical or should I not worry?

thanks in advance

Michael,
I guess your timer chip has some problem.
If I remember there is old program MSCONFIG or MSC to view IRQ and I/O ports; you could view IRQ chain and understand how your PC working.
If my mind help me, 2.nd time is user by timer tick, interrput generated ever 200ms; MSDOS doesn't use it becuase MSDOS hasn't round robin concept; if is true you can continue use your PC.

Antoniov,

Thank you kindly for your reply.

Could you please elaborate on the chip that is damaged. It controls the IRQ?

MSCONFIG is not available for before Win95, unfortunately.

Could I possibly test the IRQs to determine if they work, by connecting a sound card or modem, and determining if it functions?

Sorry,
the ancient name of MSCONFIG was MSD (MS Diagnostic).
Run it.
I have to close my internet connection, but if you have some problem again, I can see your post tomorrow.

Thanks for the reply. Would it be true that software will lock up now?

I know this is a judgement call, but would you think I should trash this PC and look for another 386.

Michael,
until PC work, doesn't make nothing.
I think you can't find any software.
If you haven't MSD, please post MSDOS version; I have old copies for V5.00 and V6.00.

Antoniov,

First I very much appreciate your help.

I ran MSD as you mentioned (I have DOS 5.0) and yes the IRQ settings are showing up.

What should I look for in MSD? What test do I need to preform.

I am sounding like a moron, but I am not familiar with DOS

Michael...I see you are new to these forums so while you await your benefactor's return, why not take some of your time and read the forum guidelines....specifically those that relate to assigning points. Then you will be able to reward the substantial efforts he is making. (hint: log in, click on the "unassigned" notation by each post)

If you desire a copy of DOS you might also pay a visit to www.bootdisk.com or www.kazungu.com. I recall that the latter was now open to the public and had DOS 6.22 on site.
I do not need to know everything. I just need to know where to go to get the information.

Michael, if your dos is IBM-DOS then the post code 1102 is related to system board.
