Hello, I have now got the RM4000 finally running. Following things I changed in the kernel: *) To find the devive: Lun scan code in scsi_scan.c Device special flags in scsi_devinfo.c The final implementation could be easy done via the flags in the scsi_devinfo.c file. *) The RM4000 make troubles when trying to write more than 1023Kbytes in one cdb. I have changed sd.c to avoid this and only use 512Kbyte blocks as maximum. The final implementation is a little bit difficult because I need some flags to detect the block size problem in sd.c, sd_init_command. Should I build the changed into sd.c?
