Does anyone know where I could find a list of all the in/out ports. It's really irritating when I don't know what a port does.

Google for Ralf Brown Interrupt List.

From what I have seen of Ralf Brown's interrupt list, it only lists the interrupts and what they do. I want to find a list of most of the ports for the commands in and out.
One of the things I want to do is setting the SVGA mode without the int 10h. Smiddy, what do you mean by PnP? |

Last time I used Ralf's list was five years ago, so things may have changed. But I recall there was also a file with ports descriptions supplied along the interrupt list.

The problem of PORTS is that they can hardly work together efficiently!! You need to use them ONE by one... Even with separated programs.. I think _________________ Groups lower your IQ |

Sorry ghfphx, I sometimes forget, PnP is short for Plug and Play. There are several documents on the web that discuss this specification. It is a bit outdate, but most all current adaptation are backwards compatible and are theoretically by default compatible with former standards. An exemple of a typical PnP device identification is:
Code: DeviceTree - 0.08.0001 Attempt to see what devices are installed... -smiddy PnP BIOS : PCI Bridge I/O Port 04D0 - 04D1 I/O Port 0CF8 - 0CFF I/O Port 0022 I/O Port 0072 - 0075 I/O Port 0400 - 040F I/O Port 0800 - 087F I/O Port 0880 - 08FF I/O Port 002E I/O Port 002F End of Device Resources RAM Memory Memory: 00000000 - 0009FC00h - Available to OS Memory: 0009FC00 - 00000400h - ROM Memory: 000F0000 - 00010000h - ROM Memory: 00100000 - 27EF0000h - Available to OS Memory: 27FF0000 - 00008000h - ROM Memory: 27FF8000 - 00008000h - ROM Memory: FEC00000 - 00001000h - ROM Memory: FEE00000 - 00001000h - ROM Memory: FFF80000 - 00080000h - ROM End of Device Resources Programmable Interrupt Controller (8259 Compatible) I/O Port 0020 - 0021 I/O Port 00A0 - 00A1 IRQ 2 End of Device Resources DMA Controller (8237 Compatible) DMA Channel 4 I/O Port 0000 - 000F I/O Port 0080 - 0090 I/O Port 0094 - 009F I/O Port 00C0 - 00DE End of Device Resources System Timer (8254 Compatible) IRQ 0 I/O Port 0040 - 0043 End of Device Resources Real Time Clock IRQ 8 I/O Port 0070 - 0071 End of Device Resources Keyboard Controller IRQ 1 I/O Port 0060 I/O Port 0064 End of Device Resources Other System Peripheral I/O Port 0061 End of Device Resources Other System Peripheral IRQ D I/O Port 00F0 - 00FF End of Device Resources Generic XT-Compatible RS-232 I/O Port 03F8 - 03FF IRQ 4 End of Device Resources Generic XT-Compatible RS-232 I/O Port 02F8 - 02FF IRQ 3 End of Device Resources ECP 1.?
