No, it isn't. I'm building RedBoot & hello, then placing RedBoot onto
diskette, halting the system, rebooting from diskette... So, fs isn't mounted
@ the moment and Linux doesn't work (of course)...
May be redboot assumes some extra data have to be arrived with filedata
while loading srec image through ttyS0? Or,
maybe, it loads some extra data while reading ext2-based file?
Is there any way to rebuild redboot so that it would display something useful
in respect to solve problem?
Thanks a lot,
Dmitry.
