I have get the current version of eCos packages via CVS

ecosconfig new pc redboot
ecosconfig import ../i386/pc/...../redboot_FLOPPY.ecm
I do not use the memory flash

make


I 've successfully compiled both redboot.bin & redboot.elf

Redboot runs from a floppy disk on 486 pc

I have two PC (486 and Pentium)that communicates through serial port(I
use the program minicom(on Pentium))

I load with the serial port the compiled program hello with the tools
of  i386-.

I have loaded in memory RAM hello with the command load.
