Hi I'm a bit new to coding C and am having a hard time following the source code to determine the exact boot sequence of the 'One'.
I do realize that the _core86.rom is the BIOS and _V86boot.exe is the boot loader. I also know that _86duino.bin is the system file and _86duino.exe is the compiled .INO file. What I would like to know is what exactly loads first, what does it initialize and what does it hand off to. I would like to be able to alter the boot process to boot to a FreeDOS prompt and load scripts for the board from there. All the bootable images make a small image and I would like to make a larger, i.e. 8G image much like a small hard drive. FreeDos supports a larger image but all the supplied images are FAT12 not FAT32 as needed for a lager disk. Please help with this if anyone has any info. Thanks in advance

When entering FreeDOS, 86Duino first runs the bootloader v86boot.exe, and then v86boot executes 86duino.exe to run the user's sketch.

You can use the 86Duino SysImage tool to build a bootable SD card, which is already a FreeDOS disk; then opening the autoexec.bat in the SD card, you will be able to see and change the boot sequence of 86Duino:)
