| 10 | * changes were necessary to adapt the code to Etherboot and to fix several |
| 11 | * inconsistencies. Also the RPC message preparation is done "by hand" to |
| 12 | * avoid adding netsprintf() which I find hard to understand and use. */ |

| 15 | * it loads the kernel image off the boot server (ARP_SERVER) and does not |
| 16 | * access the client root disk (root-path in dhcpd.conf), which would use |
| 17 | * ARP_ROOTSERVER. The root disk is something the operating system we are |
| 18 | * about to load needs to use. This is different from the OSKit 0.97 logic. */ |
