10 | * There are 5 different IPL methods | ||
11 | * 1) load the image directly into ram at address 0 and do an PSW restart | ||
12 | * 2) linload will load the image from address 0x10000 to memory 0x10000 | ||
13 | * and start the code thru LPSW 0x0008000080010000 (VM only, deprecated) | ||
14 | * 3) generate the tape ipl header, store the generated image on a tape | ||
15 | * and ipl from it | ||
16 | * In case of SL tape you need to IPL 5 times to get past VOL1 etc | ||
17 | * 4) generate the vm reader ipl header, move the generated image to the | ||
18 | * VM reader (use option NOH!) and do a ipl from reader (VM only) | ||
19 | * 5) direct call of start by the SALIPL loader | ||
20 | * We use the cpuid to distinguish between VM and native ipl | ||
21 | * params for kernel are pushed to 0x10400 (see setup.h) | ||
22 | |||
23 | Changes: | ||
24 | Okt 25 2000 <rvdheij@iae.nl> | ||
25 | added code to skip HDR and EOF to allow SL tape IPL (5 retries) | ||
26 | changed first CCW from rewind to backspace block | ||
