c

I've got some old Intel printer (Etherexpress XL ) print servers and they seem to be running an Intel OS called Cos

aka Intel Client Os i86

I've found out that much just looking in the update files from Intel. It was at least partly written in C.

How do I make a custom software image Intel Cos's boot loader will understand ?

I know a host PC xmodem's the image to the client device, and I was wondering if anyone had already either reverse-engineered this or had original info ?

or is my only recousre to reverse engineer the update file format ?
