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