It requires /FS /APIC /CD /SAP:0x20 /EIS to boot. Otherwise it stops at a line that says it is initializing devices/events/objects. APIC works providing high irqs and hypertreading works using 104a SMP Kernel. The problem at that point was very slow video performance using SNAP with with an ATI Radeon X600 Series card. I experimented further and determined that using SAP:0x25 fixed the video problem. " defect closed major Release version 3.18 ACPI PSD 3.08 unknown
