DOS ain't dead - DOS on Compaq EVO T20 thin client

DOS on Compaq EVO T20 thin client - possible? (Developers)

posted by RayeR , CZ, 08.11.2008, 17:48

I just got Compaq EVO T20 thin client (based on AMD Geode 300MHz + 16MB flashdisk + 32MB RAM) and I'm trying to run FreeDOS on it.
I know how to modify and flash firmware, it contains HDD image which is then probably emulated as normal HDD by BIOS. Original OS on the image was Win NT embedded on NTFS. I made a new hdd image and put freedos on it using bochs - it boots OK. Then I injected it to firmware but it doesn't boot :(
Only message "FreeDOS" is displayed and it hangs. This seems to hang at very beginning of bootsector exec. I patched boot drive at offset 24h to 80h but didn't helped, any idea?

btw on T20 is possible to run patched GRUB for loading Linux from USB flash so I would expect DOS should run also there...

DOS gives me freedom to unlimited HW access.
