Hey all I was running the advanced diags on my IBM XT and upon running the diags I get a 102 error anyone what this is? I am using Adv diags 2.05.

I updated to Adv diags 2.22 and error gone. Must have been the older version of the diags.

102 System board error - Timer failure.

102 System board error - Timer failure.That's a POST error code. He was referring to an error generated by Adv diags 2.05.

Yes it's a POST code too. Same for both.

According to IBM's source for the 5160 BIOS, failure of the second test of the timer results on a "101" on-screen, not "102".
(Failure of the first test results in a halt of the CPU.)

CPU never halts the test continues on. It only showed up under the 2.05 Adv Diags as noted. AD 2.22 no error

Yes, it sounds like a bug in 2.05, but surely IBM would have tested 2.05 on a 5160 motherboard before release.
If I can replicate the issue, then I will list it on my web site as a known problem.

Referenced that info but there seems to be conflicting info from IBM here (http://ps-2.kev009.com/pcpartnerinfo/ctstips/49fe.htm)


101 Main system board failure/Processor error.
PS/2 - Interrupt failure
PCC - Interrupt controller failure
102 BIOS ROM checksum error. (Try reseating the ROM chips!)
PS/2 - Timer failure or Real time clock 64 byte CMOS RAM test
PCC - System timer 2 failure

On the reference from your web site (http://www.minuszerodegrees.net/5160/post/5160_post_and_initialisation.htm) it lists the 8253 timer and 8259 interrupt controller generating 101 errors, which I verified is how it is listed in the BIOS source. The IBM error code listing has error 101 as the interrupt controller (matches your site) and error 102 as System timer 2. Things that make you go hmm.

Edit: I located the 102 error in the 5170 BIOS listing as Timer error. So where does that 102 error originate in a 5160? Reseat BIOS chips as suggested by IBM?

The system does work for the most part. Haven't seen any obvious errors

Did the problems with Norton & PC Tools go away? (for others that may wonder, you did an edit while I was doing this reply)

I found the 102 error in the 5170 BIOS source listed as Timer error. Now I'm wondering where the 102 error came from in the 5160? The error listings from the IBM document I referenced has a BIOS checksum error listed that suggests re-seating the ROM chips, not a model specific suggestion so maybe worth a try to get rid of the errors you are having with Norton and PC Tools.

Hey Russ, They only showed up when running from floppy. After I put my hardcard in there the errors went away. so right now all seems to be ok.

There are P.O.S.T. Diagnostic cards available on eBay...
