The vbios belongs to the graphics engine. Since Intel graphics chips are part of the chipset our vbios is integrated into the system bios. Any PCI card will have it's own vbios and as long as you choose one that is capable of supporting the 848x480 mode you should be fine. Also, if the chipset is an 845G (not 845GL) you probably have an agp slot as well. An AGP card that supports 848x480 would work as well.

If I use a pci graphics card, will that still have to go through the vbios? Is there a pci card out there that can program the mode directly or is this always going to be a restriction by the 845 system? I need something quick to work now :-(. damn > -Matt > > > > -----Original Message----- > From: Tom Fishwick [mailto:[EMAIL PROTECTED]] > Sent: Monday, July 15, 2002 9:12 AM > To: [EMAIL PROTECTED] > Subject: [Xpert]i810 driver on the 845 trying to do 848x480 > > > Hi there, > > I am in some rather desperate need of help.
