In the line for the DOS comm area, the hex address is 00050 to 00070 which would be 32 combinations, since the size is 512 bytes this would mean each address would represent 16 bytes or 128 bits. Is this correct? It seems like alot. Also does this have anything to do with bus width? Thank you very much, Doug Conventional memory detail: Segment Size Name Type ------- ---- ---- ---- 00000 1,024 ( 1K) Interrupt Vector 00040 256 ( 0K) ROM Communication Area 00050 512 ( 1K) DOS Communication Area 00070 2,048 ( 2K) IBMBIO System Data CON System Device Driver AUX System Device Driver PRN System Device Driver CLOCK$ System Device Driver A: - C: System Device Driver COM1 System Device Driver LPT1 System Device Driver LPT2 System Device Driver LPT3 System Device Driver COM2 System Device Driver COM3 System Device Driver COM4 System Device Driver 000F0 5,360 ( 5K) IBMDOS System Data
