973 Are you booting via USB or firewire?
974 ====================================
975 Try to boot with bootparam scandelay which delays the
976 bootup sequence so modules should have enough time
977 to initialize devices.
979 Usage examples on bootprompt of grml-iso:
981 grml scandelay -> adds the default delay of 10 seconds
982 grml scandelay=13 -> adds a delay of 13 seconds
984 Are you booting via SCSI?
985 ====================================
986 Use the bootparam scsi.
987 Usage examples on bootprompt of grml-iso:
989 grml scsi=probe -> autoprobing of scsi modules
990 grml scsi=ask -> list modules and prompt for module which should be loaded
991 grml scsi=modulename -> loads specified module (without .ko extension)
992 expert -> activate expert mode, similar to scsi=ask
994 Are you getting SquashFS/zlib errors?
995 =====================================
996 Try to boot with \"grml nodma\"
1000 Make sure the ISO itself is ok.
1001 Check the md5sum of downloaded ISO.
1002 Used a CD-RW? Make sure the medium is ok!
1004 Please report any problems you notice to the grml-team!
