Can anybody out there figure out a way to effectively bank switch the BDOS and BIOS portion of Z-System into bank 1 (or any other bank) of the HD64180 so I can push the TPA size over my cramped 49K? Any hints or helps out there would be appreciated. --Curtis R. Anderson State University of New York at Buffalo V125KJG8@UBVMS.BITNET

LRU buffering is active, hashing on hard disk directories..... Alex P Novickis Fulcrum Computer Products

Hello, Curtis, Echelon is working the bank switching problem, last I heard. Perhaps you should contact them to see how they are coming. It really isn't an easy problem at all, especially with environment descriptor and message buffer access being required for Z System operation. Rick -------
