I am trying to run LASTBYTE, an extended/expanded memory manager, but I can't get my configuration right. The manager aborts with an error complaining that "shadow ram is disabled/relocated; change setup". All attempts to change setup result in the same error, but I really don't understand what is happening in the setup process. What is set in the battery backed setup configuration? And what do the new memory managment chipsets such as NEAT do? My machine is an Emerson 386SX with Phoenix BIOS (enhanced) and a VLSI chipset (??c202), with 2MB of memory. The chip-check program provided by LASTBYTE identifies my chipset as one supported by their program. Setup is supported in ROM by the Phoenix BIOS. I want to use LASTBYTE because this memory manager offers EMS 4.0 without entering protected mode, by making use of the DMA capabilities in the chipset. The EMS manager provided with my machine apparently uses protected mode; the LANDMARK speed rating drops when I use it. The setup program has an elaborate, interactive session asking which ROMs I want shadowed, whether to enable RAM relocation, location of 64K window, enabling auto-location of 16K windows where possible, etc. Unfortunately, the manuals don't give me a clue what all this means. Any help? Should I use some other CMOS config program? Perhaps I have to write to Phoenix for a real manual? Or maybe to VLSI for spec sheets?
