Is it possible to use a USB flash memory?
If yes, is grub a good solution?

I am using an old PC and the pc386 BSP to test file system code. My
is to use etherboot. I copied it onto a floppy disk and boot from it. 
Etherboot performs a DHCP request which has the file to download in it.
etherboot image can download and boot the RTEMS ELF file.

The etherboot image I use can be found here:
