Bedford, MA Lines: 21 I am interested in running DOS and standard programs on a Virtual DOS system using a 386 base. The goal is a sort of augmented and paranoid access control over the disk (and maybe network); rather than go into that let me say for argument that I want detailed statistics on any and all peripherals while running standard programs such as Lotus, Word, WordPerfect, dBase, etc. I want to tally all writes to screen memory, all disk accesses, any bypass of BIOS such as controller or timer reprogramming, and so on. Can anyone offer insight into such an enterprise? Yes I know that performance will suffer, and a drop of 50% is OK! I have read about one or two virtual DOS's whose main goal is to switch between environs, but I want to stick in a review mechanism between the software (DOS + application) and the hardware.
