See the SRM Firmware +HOWTO at http://www.alphalinux.org/faq/SRM-HOWTO/ for more details +about SRM. + +In common with many Unix systems, the SRM code reads the first +512-byte "sector" off a disk and parses information in that +sector. The information in question is the location (start "sector") +and length of the first stage boot loader. On a Linux system, this +file will normally be called bootlx. + +SRM will load and execute the first stage boot loader, and from that +point the system should be able to find the normal OS kernel and start +up fully. + +To use the Alpha boot support code in genisoimage, simply specify the +location of the first stage boot loader (relative to the CD root) +using the -alpha-boot command line switch: + +genisoimage ... -alpha-boot boot/bootlx -o alpha.iso files + + |
