Ive running a Xeon X5650 on it, but VT-d is routed through bios(dmesg told me), and the DMAR-Table is broken. On the xen page i've found this "ASUS P6T Deluxe (Intel X58 chipset) requires (currently non-public) BIOS update to correct DMAR-table issue". Does anyone know if there is a unofficial bios with corrected DMAR-Table? google is not my friend^^ didnt find anything useful :( greet Spirit </pre> </blockquote> I have the same motherboard and also sought that bios, without success. There is however someone else who may have tried it <a class="moz-txt-link-freetext" href="https://bbs.archlinux.org/viewtopic.php?pid=1487138#p1487138">https://bbs.archlinux.org/viewtopic.php?pid=1487138#p1487138</a> See Alex's response suggesting use of <pre><code> memmap=nn[KMG]$ss[KMG] [KNL,ACPI] Mark specific memory as reserved. Region of memory to be reserved is from ss to ss+nn. Example: Exclude memory from 0x18690000-0x1869ffff memmap=64K$0x18690000 or memmap=0x10000$0x18690000</code></pre> I haven't tried this myself so would be interested in your feedback :) </body> </html>
