Using Bootloader Autoboot Function
The Keith & Koep bootloader for Trizeps-modules is able to automatically boot files from SD/MMC or CompactFlash storage cards. Autoboot through CompactFlash cards is not supported by Trizeps2 and 3.
To use this functionality the storage card needs to be formated as FAT12,FAT16 or FAT32.
Create an autoboot.bat-file in the root-directory of the primary partition.
Fill autoboot.bat with valid bootloader commands.
Put the card into the socket and power on the device. The bootloader will automatically search for an autoboot.bat file and execute it.
