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