This stores the ''System Mode'', ''Affinity Mask'' and ''Ideal Processor'' values in one byte. They are stored as follows:
+
{| class="wikitable" border="1"
u8 Flag0 = (SystemMode << 4 | AffinityMask << 2 | IdealProcessor);
+
|-
And can be retrieved as follows:
+
!  Bits
u8 SystemMode = (Flag0>>4)&0xF;
+
!  Description
u8 AffinityMask = (Flag0>>2)&0x3;
+
|-
u8 IdealProcessor = (Flag0>>0)&0x3;

| 0-1
 +
| Ideal Processor
 +
|-
 +
| 2-3
 +
| Affinity Mask
 +
|-
 +
| 4-7
 +
| System Mode
 +
|}
    
In the exheader data, the IdealProcessor field is a bit-index, while in the accessdesc the IdealProcessor field is a bitmask. When the bit specified by the exheader field is not set in the accessdesc field, an error is returned. "if((1<<exheaderval) & accessdescval == 0)return error"
