It’s been a while but it has been moving on slowly. I have got to the stage of running some win32 code finally. I have a small shell (which doesn’t do much yet), but the shell is 100% win32 code (written in Delphi). Basically, I have enough of the win32 api to read/write to the console, read from files, list directory contents and change the current directory. Next on the list will be to fire up another application. I’ve got tcp/ip built into the kernel on this incarnation rather than loading via dll/device driver, so heading down the monolithic kernel path for now which suits embedded type apps.
Also, of interest, I got myself a small test system (wafer-lx) for embedded work -see pic. It has an AMD LX-800 CPU, 1 gig of ram, and a 4 gig hi speed Flash drive. This little beauty packs quite a punch – more details are below. I’ve got Classios to boot up on it with full TCP/IP networking. I can even boot it via DHCP/TFTP using the PXE protocols. P!
Some more pics.

I have been –sort of– following this project since the Petros->Classios name change, and I am wondering what it would take you to get this to a more usable state.
By useful state, I mean basically this: It does file IO, has TCP/IP. That’s about it for an embedded-like hardware such as the one you used above–video/graphics, sound etc. can wait.
So. What is it?
Is it lack of funds, or inspiration?
A mix of things have delayed me. There will be a new post about it as there have been some exciting developments this week. Keep tuned…
P!

? Then, this might interest you. http://petertattam.com/?p=10 http://petertattam.com/?p=15 You might even ask the guy whether he’ll opensource it –and, when. [...]
