4.12 Direct SCSI access

If you have an Acorn SCSI adapter, or an alternative which supports the same SWIs (check with your SCSI adapter supplier), you can use direct SCSI support. The aim of this is to allow SCSI hard disks which have been formatted and used on a PC to be read and written to by the PC Card. 

If you want to connect a PC-formatted SCSI disk, you should: 

  1. Select the DOS format SCSI drive radio button.
  2. Enter the device number, that is, the drive’s number on your SCSI chain.
  3. The software will configure itself automatically to the shape of the drive.
  • You may experience desktop problems because RISC OS thinks that this disc is a SCSIFS drive which it cannot read properly. To cure this, the PC hard disk should have its SCSI ID set to a higher number than any other RISC OS drive on the SCSI chain, and you should use:
      *Configure SCSIFSdiscs n 
       
    to reduce the number of disks by one (that is n should be the number of discs present on the SCSI chain minus one).
