Hi, I have a Tyan s2895; Linux complains on boot: Your BIOS doesn't leave a aperture memory hole Please enable the IOMMU option in the BIOS setup This costs you 64 MB of RAM Mapping aperture over 65536 KB of RAM @ 4000000 But I have triple-checked, I have "IOMMU: enabled" in my BIOS config. Quid? -- Lionel
