Here you can find some examples that are written in Bascom-8051 and Bascom-AVR. Examples for the 515/535-mainboard standalone or with the backplane in combination with the I2c- or Steppermotorboard. Furthermore examples for some boards I have tested.

AVR-DOS info
Franz Josef Vögel has made AVR-DOS.
 A FAT16 filesystem for Compact Flash Card and Harddisk written in assemly and Bascom-AVR. The AVR-DOS.LBX-library is part of Bascom-AVR 1.11.74, but if you are going to use it for a commercial project you have to pay a license fee.

This is the ATA Hard Drive Controller from www.edtp.com
Fred Eady of www.edtp.com was a major sponsor for the project to get AVR-DOS running on a harddisk. This ATA Hard Drive Controller board with a ATmega128 and a RTL8019AS ethernet-chip has a connection to a ATA harddisk.

Have adapted the original AVR-DOS file, which can be found at the site of Franz Josef Vögel  to work on the ATA Hard Drive Controller from www.edtp.com
If you want to use the AVR-DOS-library with the EDTP-board this is what you need:
