PCI-Based Power Macintosh: LAT Compatibility (1/96)

This article describes an update on the status of LAT compatibility with the PCI-based Power Macintosh computers, the 7200, 7500, 8500, and 9500.
There have been reports of compatibility problems with the PCI-based Power Macintosh computers and LAT that were initially believed to be related to Open Transport. Further investigation by the Open Transport team and DEC's PATHWORKS team has revealed there was an obscure bug between LAT and the Time Manager that manifested itself on some of these new computers. Open Transport was not the reason LAT did not function properly. The problem has been resolved in an update of LAT available from Digital.

For PCI-based Power Macintosh computers with Open Transport you must have Open Transport v1.0.6 or later. With this setup, most of PATHWORKS works properly, including DECnet. The problem was with LAT.

Do not use Easy Install for PATHWORKS v1.3; perform a Custom Install, and deselect MacTCP and LAT. If you have included them by mistake, they can remove after restarting your Macintosh. DO NOT open the LAT Tool or LAT control panel before removal. LAT v1.3 crashes PCI-based Power Macintosh computers, and these computers come with Open Transport TCP/IP, so MacTCP is not needed and should not be installed.

For LAT functionality, you need to update to LAT v1.3.1, which comes from Digital. LAT v1.3.1 also requires Open Transport v1.0.6 or greater.
