Hi, I am trying to setup a 9100A unit. The initial hard disk was defective. I had a "missing hard drive" error message. I've upgrade the roms to the V5 version and setup a SCSI2SD drive. I was able to format the disk with service disk 1.4 Whenever I try to boot from the system disks (tried original disks 4.1, images from 6.0 and 6.1), I get an error: Error 243 loading /dd/rom/appl I can skip it but then then I get more errors: root: appl missing root: Can't start application Path Name not found And the unit freezes at Initializing system. Error 243 is a CRC error based on the documentation. The floppy drive seems fine since I can load service disk 1.4. I thought that I did not restore the images properly but since I also get the error with original 4.1 disks, I am not sure what I can try next. Did anyone have had a similar problem ?
