[Freedos-kernel] feasibility question about embedded FreeDOS in my hobby project

[9000 V. <va...@gm...>]

Hi list,
  I am developing a hobby project where freedos kernel might be a nice
fit. There are CPU (80188), memory (256K,  512K, or even 1M if
needed), one serial line and IDE (barely some I/O ports?)  or SCSI
(this is ready on my board) interface on board. Now I want to hook an
HD with FAT file system to the board. The board will have a small bios
to load a program from the HD and execute it. The program will then
use the HD to hold configuration files and to store some data. A FAT32
file system is super, but a FAT16 is OK if FAT32 is difficult.

  My question is whether this goal is feasible *to me*. I can
trim/integrate/modify pre-existing codes. I can write codes that make
the raw R/W to the HD. Anything else (eg, serious kernel hacking) will
be a big challenge thus is not feasible *to me*. I know that FreeDOS
kernel provides the functionality, but I don't know how much I need to
do before a trimmed FreeDOS kernel can run on my rather minimal
hardware. Thank you.
