1029 Are you booting via USB or firewire?
1030 ====================================
1031 Try to boot with bootparam scandelay which delays the
1032 bootup sequence so modules should have enough time
1033 to initialize devices.
1035 Usage examples on bootprompt of grml-iso:
1037 grml scandelay -> adds the default delay of 10 seconds
1038 grml scandelay=13 -> adds a delay of 13 seconds
1040 Are you booting via SCSI?
1041 ====================================
1042 Use the bootparam scsi.
1043 Usage examples on bootprompt of grml-iso:
1045 grml scsi=probe -> autoprobing of scsi modules
1046 grml scsi=ask -> list modules and prompt for module which should be loaded
1047 grml scsi=modulename -> loads specified module (without .ko extension)
1048 expert -> activate expert mode, similar to scsi=ask
1050 Are you getting SquashFS/zlib errors?
1051 =====================================
1052 Try to boot with \"grml nodma\"
1056 Make sure the ISO itself is ok.
1057 Check the md5sum of downloaded ISO.
1058 Used a CD-RW? Make sure the medium is ok!
1060 Please report any problems you notice to the grml-team!
