:if one can make /dev/ram and access it as a block device can one make a
:ram disk or is this still impossible under irix?
At least as of 6.5.20, it's still not possible. Look in
/var/sysgen/master.d/mem and notice that the flags there show that
it is a character only device. Then search the other files there
to see if there is anything else there that has a major device
number of 1 and that is a block device. For example,
cd /var/sysgen/master.d
nawk '{sub(/\*.*$/,"")}; /^ *$/ {next};
$3 ~ /1/ {print FILENAME, $1, $3, $4}' *
and if you scan the output you'll find zippo of interest.
(Sorry, you'll get a number of false hits, but it's a quick hack
expression and you get what you pay for ;-) )
