I've not yet tried executing linexec as there is no kernel to suit 2210
yet. Don't forget that linexec is just a wince-executable bootloader for
linux (not the whole box-and-dice).

However, the ReadMe.txt for linexec
http://cvs.handhelds.org/cgi-bin/viewcvs.cgi/*checkout*/linexec/ReadMe.txt?rev=HEAD&content-type=text/plain
says:
"If a screen with Hello World appears, there was a problem in booting.
Check filenames."

also, WhatsNew.txt
http://cvs.handhelds.org/cgi-bin/viewcvs.cgi/*checkout*/linexec/WhatsNew.txt?rev=HEAD&content-type=text/plain
says:
"Parameters are read from \CF Card\params file, the format can be seen in
boot.cpp file.v1.0"

And further, boot.cpp
http://cvs.handhelds.org/cgi-bin/viewcvs.cgi/*checkout*/linexec/boot.cpp?rev=HEAD&content-type=text/plain
includes lines like:
#define BOOT_LOGO_PATH "\\My Documents\\booting.bmp"
#define BOOT_LOGO_PATH_CF "\\CF Card\\booting.bmp"
#define BOOT_LOGO_DONE_PATH "\\My Documents\\done.bmp"
#define BOOT_LOGO_DONE_PATH_CF "\\CF Card\\done.bmp"

and defines the format of the params file as:
 char cmd[200],image[50],initrd[50]

The Axim X5 page at
http://handhelds.org/z/wiki/DellAximX5
says:
linexec can pull boot files from anywhere (CF/SD/MMC, wherever)

It probably would have saved me some time earlier if I had read this page
about installing linux on the axim: http://www.clanbv.org/public/axim.html
In particular, on that page is a link to
http://www.clanbv.org/public/dospart.tgz
which includes a 'params' file containing:
\CF Card\zImage
\CF Card\initrd
root=/dev/ram0 ro init=/linuxrc console=tty0
(which seems to be the wrong order(?) compared to the definition above, but
anyway) note: dospart.tgz includes (a version of) linexec.

I hope I havent wasted too much bandwidth :), but at least *I* have a
better idea of how it's supposed to be done now ;)) heh.***ONCE WE HAVE A
(semi?)WORKING KERNEL AND RAMDISK*** ie. I'm not too sure if trying 'any'
kernel/rd combo is such a good idea.
