I have CentOS 5 and from what I have been able to understand from the man page of redev
redev -r or ramsize can be used to display the ramsize
rdev -v or vidmode can be used to display the video mode
however for me no options of rdev are working except 'redev ' given without any arguments
outupt of rdev -r or rdev -v just prodeces the rdev -h help page
what am I doing wrong ?
