I don't know why nobody said anything, I just work here. This message was gatewayed to BIX ( BYTE Information eXchange) , where the following reply was posted. I thought the net would be interested. -- begin reply I'm not sure what this message was about, and I don't have the original one to read. The checksum feature was a problem in the ROM, not the System file. I documented this issue in Tech Note 258 "Our Checksum Bounced." There is no SCSI driver in the System File. A SCSI driver resides in the SCSI installer utility (i.e. HD Setup) and is installed on the hard disk where it remains. Running any version of the system will not change the driver. This can only be done by running the SCSI utility again, and updating the driver or initializing the disk. Nothing in any of the 6.0x releases has changed SCSI. I do not understand how running System 6.0.5 could change anything (although it is required for the IIfx for many reasons.) There's a missing piece to this puzzle. If Kevin has read Tech Note 258, and still has a problem then I'd like to hear the details. Jim Reekes E.O., Macintosh Developer Technical Support 1:20:36 PM July 27, 1990 --end reply Laurence H.
