I just purchased a Paradise VGA 1024 board, with 512K of memory, to replace my old Video 7 VEGA VGA board, thinking that I'd reap considerably increased speed from the 16-bit bus vs. the old 8-bit bus on the Video 7. I've noticed that when I use "setcolor -s on" to enable hardware scrolling, the Paradise board appears to scroll more slowly than my old VEGA VGA with hardware scrolling enabled. I have the board configured to automatically use the 16-bit bus if available, so I assume that it is doing so. Does anyone have any idea what may be going on here, or a suggestion about something that I might be doing wrong? I remember reading a note about commenting out the VGAROM line in vpix.cnf with certain graphics boards a while back in this newsgroup. Under what circumstances is this advisable, and what are the pros and cons of doing this? Lastly, does anyone out there have experience using this graphics board with ISC's new 256-color X server? How does the board perform? Thanks for any information/suggestions. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Brad Karp | DISCLAIMER: | | my 386: karp%softshop.uucp@cs.yale.edu | ----------- | | via Yale CS Dept: karp-brad@cs.yale.edu | The views expressed in the text |
