K8D Master3-FA4R (MS-9161)	AMD 8131/8111 / 2x Socket 940	Fully functional	Guy Helmer	5.4-RELEASE	Tested with dual Opteron 252 CPUs. SiI SATA interface untested (used SCSI drive on Adaptec 29160 instead).
K8N Neo2 Platinum	nVidia nForce 3 / Socket 939	Does not boot with ACPI.	Roman Divacky	6-CURRENT (April 2005)	Broken IRQ tables in BIOS, ACPI does not work, PS/2 keyboard unusable. Boots with ACPI enabled in RELENG_5.

X6DA8-G2	Intel E7525 / 2x 604-pin FC-mPGA4	Functional	Erik Power	5.4-RELEASE	The default kernel included with the 5.4-RELEASE amd64 distribution does not see hard drives attached via the Intel ICH5R SATA/ATA controller. Workaround is to boot using safe mode during install and when booting default kernel. After compiling a kernel, ata(4) works fine and the system boots normally. SMP kernel installed and working. LAN, audio, USB working. ZCR not tested (no driver for Adaptec 2010-S), AIC7902 U320 SCSI not tested.
X6DHR-8G	Intel E7520 / 2x 604-pin FC-mPGA4	UP kernel must be booted in "safe mode" (or hint.apic.0.disabled="0"). SMP Functional.	Guy Helmer	5.4-RELEASE	Boots stock SMP kernel. Boots UP with tweak noted in "issues" column (tried both BIOS revisions 1.2 and 1.2a). LAN working. UHCI controllers seem to cause interrupt storm. AIC7902 U320 SCSI operates successfully with Seagate ST373207LC drives (gives an "Invalid Sequencer interrupt" when probing the SCSI bus, but then continues).
