Buffer Offset The Buffer Offset field may be set to any address in the buffer, but must obey the specified Offset Boundary.
Allocation The amount of data to return. Allocation Length + Buffer Offset must be within the buffer size. Length
Memory sizes:
Main Buffer Memory Size: 128 MB, reported size FFFFFFh.
Because the buffer is greater than 16 MB, additional buffer IDs have been defined to allow the buffer to be accessed in 16 MB segments. these are as follows:
| Buffer ID | Address |
|
| 20h | 00000000h + Buffer Offset (same as Buffer ID 00h) | |
|
|
| |
| 21h | 01000000h + Buffer Offset (in other words, +16 MB) | |
|
|
| |
| 22h | 02000000h + Buffer Offset (in other words, +32 MB) | |
|
|
| |
| 23h | 03000000h + Buffer Offset (in other words, +48 MB) | |
|
|
| |
| 24h | 04000000h + Buffer Offset (in other words, +64 MB) | |
|
|
| |
| 25h | 05000000h + Buffer Offset (in other words, +80 MB) | |
|
|
| |
| 26h | 06000000h + Buffer Offset (in other words, +96 MB) | |

| 27h | 07000000h + Buffer Offset (in other words, +112 MB) | |
