1020 Are you booting via USB or firewire?
1021 ====================================
1022 Try to boot with bootparam scandelay which delays the
1023 bootup sequence so modules should have enough time
1024 to initialize devices.
1026 Usage examples on bootprompt of grml-iso:
1028 grml scandelay -> adds the default delay of 10 seconds
1029 grml scandelay=13 -> adds a delay of 13 seconds
1031 Are you booting via SCSI?
1032 ====================================
1033 Use the bootparam scsi.
1034 Usage examples on bootprompt of grml-iso:
1036 grml scsi=probe -> autoprobing of scsi modules
1037 grml scsi=ask -> list modules and prompt for module which should be loaded
1038 grml scsi=modulename -> loads specified module (without .ko extension)
1039 expert -> activate expert mode, similar to scsi=ask
1041 Are you getting SquashFS/zlib errors?
1042 =====================================
1043 Try to boot with \"grml nodma\"
1047 Make sure the ISO itself is ok.
1048 Check the md5sum of downloaded ISO.
1049 Used a CD-RW? Make sure the medium is ok!
1051 Please report any problems you notice to the grml-team!
