yup - i posted a few messages last night, to the other WinCE thread - i thought you had read them.
Summary - it works and looks pretty , but no USB or networking (yet).
Details - create a new CE Platform Builder project, name it, select the MAXALL predefined configuration, select the 'Release' model, NOT the 'Debug' version; clean, build headers, build image file NK.BIN. make an MS-DOS bootable CF card (at least 16 meg - I used 32 meg) and place the following files on it:
IO.SYS from Win98
MSDOS.SYS from Win98
HIMEM.SYS from Win98
CONFIG.SYS with only one line: "DEVICE=HIMEM.SYS"
LOADCEPC.EXE from the directory C:\WINCE300\PLATFORM\CEPC\BOOTDISK
NK.BIN from the directory C:\WINCE300\PUBLIC\<your project name>\RelDir\X86_Release
AUTOEXEC.BAT with only one line : "LOADCEPC.EXE /L:800x600x16 NK.BIN"
The LOADCEPC.EXE syntax was the issue. The help message returned from the utility by LOADCEPC /? displays an incorrect syntax for the /L: display definition switch. I found the correct syntax inside the AUTOEXEC.BAT file in the directory C:\WINCE300\PLATFORM\CEPC\BOOTDISK
Of course, you could always do without the AUTOEXEC.BAT file, and key in the LOADCEPC command line by hand. Good luck, and let me know what else you find out...
