SuperProbe ? XFree86 -probeonly ? In case it'll help, here's my effort to help someone who wrote in to the Linux Gazette Answer Gang with a possibly related (?) problem: > Upon install, (RedHat) Linux 7.3 doesn't recognize the intel845GL video > card that came with our GX260.

The i845G and i845GL integrated video/motherboard chipsets are the latest in that model series, replacing the i810/i815 desktop chipset (which used a i752 graphics core) and a mobile-computing variant called i830. During development, the i845G/i845GL series was dubbed "Brookdale-G". Near as I can tell, the only difference between the i845G and i845GL is that the latter can't support the higher 533 MHz front-side bus speed, nor AGP. That's actually (mildly) good news for you, because it simplifies the XFree86 support issue. Like the i810, i815, and i830 series before it, the i845 series omits dedicated video memory, and instead borrows from system RAM (slightly impairing memory bandwidth and reducing free RAM). On the bright side, the design reduces hardware costs. As with the i810/i815 series, you'll undoubtedly need /dev/agpgart kernel support. I noticed an agpgart kernel patch mentioned here: http://www.jongans.com/gateway1450.html The classic symptom of lacking AGPgart support for i810 and derived chipsets is that you can't use video modes that require more than 1 MB video memory. This page mentions i845G support being added to the XFree86 i8x0 CVS (prerelease) driver, around May, which means that won't emerge as a precompiled offering until the next XFree86 release: http://xfree86.desiato.de/xfree86/cvs/changes.html But there's another option: Intel advises (http://www.intel.com/support/graphics/intel845g/linux.htm) that you should use the "vesa" SVGA driver while waiting for the next XFree86 release. I.e., change the Drivers line to say: Driver "vesa" -- Cheers, My pid is Inigo Montoya. You kill -9 Rick Moen my parent process. Prepare to vi. [EMAIL PROTECTED] _ Philippine Linux Users Group.
