| 5 | help |
| 6 | Some "legacy" VGA devices implemented on PCI typically have the same |
| 7 | hard-decoded addresses as they did on ISA. When multiple PCI devices |
| 8 | are accessed at same time they need some kind of coordination. Please |
| 9 | see Documentation/vgaarbiter.txt for more details. Select this to |
| 10 | enable VGA arbiter. |

| 17 | Reserves space in the kernel to maintain resource locking for |
