First 64 bytes of BAR 0 as read by the driver at probe (Thunderbolt-attached Quantum 2626, card 4). Use for reverse-engineering register layout (compare with pae_quantum.sys or experimentation).
| Offset | Value | Notes |
|---|---|---|
| 0x00 | 0x00000000 | |
| 0x04 | 0x01030060 | Non-zero; possible ID/version or config |
| 0x08 | 0x00000010 | |
| 0x0c | 0xffffffff | Likely unimplemented / read-as-one |
| 0x10 | 0x00000000 | |
| 0x14 | 0x00000000 | |
| 0x18–0x3c | 0xffffffff | Likely unimplemented |
