NettetNot all power of two bases have an integral number of groups that fits 16 bits; for example, the octal base has 5 groups of 3 bits that account for 3·5 = 15 bits out of 16, leaving a partial group of 1 bit 3. The algorithm is simple, we isolate each group with a shift followed by an AND operation. NettetThere is nothing intrinsically protected about 32 bit code - it all depends upon the OS. You can still call interrupts like int 16h or int 21h, but you cannot then call Windows functions at the same time; it has to be one or the other.

I want to use the functions keys to change the active page, but i want that int 16h still works after i edit the IVT. Here is the algorithm i used to do this: main: * disable interrupts. * store old keyhandler at [bios_int_16h_segment] and [bios_int_16h_offset] Nettet[i] As you'll see for yourself, 16-bit programming is slightly more difficult than 32-bit programming.
