Flags
| Bit | Platform class |
|---|---|
| 0 | Podules supported |
| 1 | PCI supported |
| 2 | Multiple processors supported |
| 3 | Software control over PSU |
| 4 | OS runs from RAM |
| 5 | OS uses rotated loads |

Notes
If bits are set, it provides additional information about the hardware platform.
If both bits 5 and 6 are flagged as valid (in R2) but neither are set (in R1) then it indicates that the OS only performs aligned memory accesses. If necessary, OS_PlatformFeatures 34 can be used to determine which alignment modes are supported by the CPU.
