No data loss is a good thing! That was my biggest worry, as I have no documentation for the addon card case. Out of curiosity, did the LED usage change at all before and after the patch, or was it totally unaffected. I would guess the latter. Unfortunately, what documentation I do have shows (briefly) that add on cards implement their LED via a different mechanism. If I knew the addresses for the flash read and write strobes (FL_RDN and FL_WRN), I might be able to work something out. So as it stands, there is not much hope for the people with addon cards. > If you require more information, don't hesitate to contact me. Thanks, I will. I have emailed Silicon Image in the (slim) chance that they will provide me with the information I require. If they come through then I might be able to whip something up and have you test it. If anyone has any data on the 3112a (or 3512 as I believe they are register compatible) and isn't bound by an NDA, I'd like to hear from you. -- Aric Cyr <acyr at alumni dot uwaterloo dot ca> (http://acyr.net) gpg fingerprint: 943A 1549 47AC D766 B7F8 D551 6703 7142 C282 D542
