Hal deamon..

I have install centos on my server,.. then after rebooting 2 ,3 times , hal deamon cannot start, and system hang on boot.. when i google, i found the solution which is off the hal daemon service... my question is, what is the effect if i off the deamon service ?:confused:

tq

without HAL, a lot of your hardware may not be detected.

my server run correctly after I off the hal daemon service.. & seems the server works fine.. I also check some hardware such as NIC & RAID , and it also works fine.. I need details explanation about HAL Daemon Service... pls..
