Fresh Clean Flash of the BIOS to highest revision
Initialise in the BIOS to restore all defaults (you will need to redo the cache disable hex)
Use the ps2.exe thinkpad dos configuration utility to make sure everything is on the right addresses and irq etc.
Clean install of XP.
If it still fails its a systemboard error.
I'd follow Sharedocs gut instinct on this. There is something wrong with the motherboard of your pad.
It seems, I have found the reason on which does not work USB!
I looked through the list of interruptions in system and have seen a strange situation, - 9 interruption has been appointed to five devices!!!
The list of interruptions which has given out SiSoftware Sandra:
0: The system timer
1: Standard (101/102 keys) or keyboard PS/2 Microsoft Natural
3: ThinkPad Modem
4: A serial port (COM1)
5: IBM ThinkPad fast ÈÊ-port
7: Audio codec Crystal WDM
8: CMOS and hours
9: Crystal SoundFusion (tm)
9: Intel (r) 82371AB/EB PCI - USB the universal host - controller
9: Microsoft ACPI-compatible system
9: Texas Instruments PCI-1251 CardBus the controller
9: Texas Instruments PCI-1251 CardBus the controller
11: ThinkPad Digital Signal Processor
12: IBM PS/2 TrackPoint the trackball
13: The processor of the numerical data
14: Primary channel IDE
15: Secondary channel IDE
In WinXP conflicts has not caused, but also USB does not work, though the sound works perfectly! I did not check PCMCIA slots, since I have no PCMCIA cards.
Whether is it possible in BIOS to renominate interruptions?
Probably, it can be made in section Extended CMOS-> PCI IRQ Data.
What can you say about it?
Beforehand I thank you for the help!
