OS development using serial port, parallel port

[lets sexx]

Hello Gurus,
Do you know of any tutorial or site that teach on how to write and read to the hard disk of Test Computer from Development Computer thru serial port or parallel port or lan card. I want this because I don't trust Bochs or any emulator. I will use two computers in os development, one is Developer computer and one is the Testing computer.
The development computer is running Windows or Dos and the Test computer has just the bootsector code ;D, bootloader and simple Hello world OS. The Developer computer will write the newly coded Kernel or whatever to the hard disk of Testing computer and send a command to reboot it.

Hoping for nice answer
Love
Christy

Install some regular OS on the test computer and use communications software to transfer files. That is, unless you want to put serial port, hard disk and file system code into your boot sector...

you could put it in the second stage though, as a sort of network booting over serial cable.

GRUB will do this -- well, it will do network boot over a network at least.
