I right click on the desktop, go to active desktop>>customize>>settings>>advanced>>RIVA TNT and there is no bios version, just says "<unavailable>" I haven't flashed any new bios for the card yet, so it has whatever came in the gateway system. Also, how do i find out if it has a control block number less than 3 or not for the new bios util? I found a 2.04.24 for SDRAM version at the X-bios site. Will a new one improve performance?<br> <br> P!!400mhz 100mhz FSB<br> 192mb SDRAM 100mhz<br> STB Velocity 4400(16mb TNT RIVA)<br> Det 21.88<br> SBPCI128D<br> Win98 First Edition
