I have a quick question. Since I can't reach Adaptex (Roy Neese's machine) anymore for anonymous login, I will ask here in the hopes that someone has an answer. We wish to use a 1542 with a high speed CPU. Specifically, a Cached 25Mhz 80386 machine. What problems, if any, am I likely to run into doing this? I know the 1542 is a third-party DMA board, which implies that it will do it's own thing with the bus. Will this get me in trouble with the cache? Is this possible, and if so, what should I watch out for? Secondly, does anyone have the programs that were on adaptex to diddle the "mode pages"? I specifically want to get the read-ahead turned on for either a CDC or Maxtor fixed disk. Replies appreciated; users who actually have this combination working even more appreciated. If you DO have this combination working please indicate the configuration you are using (motherboard, etc).
