[ECOS] how to check my modifications to the kernel without a board?

Thank you so much for your help!! But I still not very clear about
some problems.

1. If "Redboot does not use the kernel" , does that mean if I want to
see the result of my modification, redboot is no help. But if without
the redboot, can I still use the VMware to run the ecos? Because I
only see the examples about how to run the redboot on VMware.

2. After these steps:
        " ecosconfig new pc_rltk8139
          edit ecos.ecc and change CYG_HAL_STARTUP to floppy
          ecosconfig tree
          make -s tests "
    and compilation of ecos, I also need to run some applications to
verify my   modification( like get some calculation results). How I
can run the applications and see the results?

Thank you!!!
