AppleTalk work-around explained Apple's Mac OS 8.1 Late Breaking Tips TIL discusses how to turn off AppleTalk for those cases where, even after apparently turning it off, you still get a "serial port in use" message (a problem previously covered here on MacFixIt).

Omar Shahine, who had reported this problem to me earlier, notes that this is not an Open Transport 1.3 problem. It is a more general problem with Mac OS 8.1. He also claims that this problem may not be restricted just to GV's 56K card.
He has now gotten a confirmation from Global Village, who replied: "Eeek, you're right, I'll let you know what we find and when a fix … Read more

FWB is working on an update to HDT 2.… Read more
"CD-ROM Tookit's disk cache gets confused by HFS formatted volumes. The first time you attempt to mount a CD after upgrading to HFS , CD-ROM Toolkit presents a dialog box stating that, due to disk damage or severe disk fragmentation, Toolkit's disk cache cannot be used.
FWB's suggestion is to open CD-ROM Toolkit and turn OFF the "fast" selection for your CD-ROM drive. This turns off all disk caches.'
FWB reports that they are working on a fix and hope to have it uploaded to their web site soon. (Thanks, … Read more
Asante now has a web page, called "Important Information for Mac OS 8.1 Users," that confirms this. As an interim solution, you can use "a special version of NetDoubler (beta) 1.5.1B2 that works with Mac OS 8.1 by temporarily switching off acceleration while you perform a Finder copy from Server to Client." (Thanks, Version Tracker).
