I have a HP PC with Award Bios. This BIOS provides a maximum of 16 MB to be reserved for Graphics. I have 320 MB RAM and would like to increase the amount of RAM reserved for Graphics. The HP site has got only the old version of BIOS (relase date -2001). What should I do to increase the RAM reserved for Graphics (if suppose I go for BIOS upgrade). What precautions should I take while updating the BIOS?
