Topic: multiface pcmcia cardbus and thinkpad t60: don't update t60 BIOS!
**EDIT: Prolem solved! It had nothing to do with BIOS flashing. An Ethernet driver update was the culprit. See post below.**
i updated my thinkpad t60 with the software update tool provided by lenovo. this includes a BIOS update (BIOS flash).
i did this before with the multiface pcmcia card inserted - afterwards i got constant dropouts. only way to solve the problem was to reinstall windows XP! [ see here: http://www.rme-audio.de/forum/viewtopic.php?id=1778 ]
now, this time, i did a BIOS update without the pcmcia card inserted - i thought that should be safe. The same thing happened! constant dropouts since then. A Multiface driver update does not solve the problem. so i will have to do a complete system reinstall again (great, all my vst are C/R, i am in for two nights at home doing the C/R thing).
so: do not ever update your BIOS on a thinkpad t60 if you want to keep a working multiface driver!
