Now: I upgraded to Soyo D6IBA motherboard (Bios 1.4, latest) with BX chipset and somehow the display adapters are mis-configured badly. I believe that the primary adapter's display memory is not seen at all. Both XFree and MetroX servers report 0 kilobytes of display memory and trying to "fix" it by manually telling the amount of memory does the same as with the probed 0k: servers hang the system. This might be a problem with BX chipset and probing of the PCI cards incorrectly. This with 3.0-REL With 3.1-REL, even the standard atk* console fails, after kernel is loaded absolutely nothing comes to either of the displays and keyboard is hung. This is a bit annoying as all this worked before, plus win NT 4.0 still works fine both with one display card only AND multi-headed with both cards. I even tried to upgrade Matrox BIOSes to the latest (3.0) which did not change anything. I even tried with MSI motherboard, Model MS-6120 and the symptoms were the same. I will try with other Soyo BX motherboards next week. >How-To-Repeat: Try BX equipped PII motherboard and two Matrox Milleniums (PCI). Try MetroX or the standard XFree86 server with the both cards, alter "VGA enable" DIP between those two. >Fix: None known, unfortunately. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
