Subject: cromemco: This gets our boot disk to the bootdev: prompt
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=89985b6ead310a4aff5fe0dc79bc17579f442096;p=FUZIX.git

cromemco: This gets our boot disk to the bootdev: prompt

Unfortunately we don't seem to have any interrupts or tty activity on reading
so this needs some further research.
