This speeds up BIOS calls, and I would normally recommend that this option be turned ON for improved performance (in this case video performance). >2) Scratch Ram Option: If required, BIOS will use 256 bytes of RAM > 1) Using BIOS stack area at 0030:0000 > 2) Reducing base memory size by 1KB > Which option should I use. I am running with 2 megs of 80ns SIPPs This seems like a very minor point. It was probably put there for compatibility purposes. Use option (1), and if you have any trouble, switch to option (2) which will be safer but will require 1K of memory (no big deal). >3) Main Bios Shadow: Enable or Disable > Again, any help would be appreciate. Same as for question (1). Enabling it will improve machine performance. Disable it if it causes any trouble (i.e., machine dying). However, you shouldn't have any trouble with it turned ON. +==========================================================================+ | Noam Mendelson ..!agate!ucbvax!web!c60b-1eq | "I haven't lost my mind, | | c60b-1eq@web.Berkeley.EDU | it's backed up on tape | | University of California at Berkeley | somewhere." |
