greetings does the list at this url cover *all* options or are there some hidden or newer ones by chance? http://www.centos.org/docs/4/html/rhel-ig-x8664-multi-en-4/ap-bootopts.html i am playing with CentOS 4 on some Compaq dual PIII hardware. The first unit is an 1850R with dual 500Mhz. If you need more info please let me know. it is a basic unit with raid controller and a Gig of DRAM etc. may i ask what others are putting in their "additional boot options" so that the units can he remotely shutdown to power off and/or rebooted without hanging please? also, any _extra_ tips and tricks are certainly welcome. again, i am grateful to those people that have been helping me off-list as well! take care and kind regards, -- Robert Hanson Abba Communications http://www.abbacomm.net
