How to boot Previous using a single partition image file

[faxmodem]

Hi,

I'm new to Previous (pun unavoidable) and it's really awesome !
I would like to know what are my options for the following use-case.
I dumped a NeXTcube's partition onto a file and would like to boot it.
Unsurprisingly, the virtual cube fails to boot:

    NexT>bsd
    boot sd(6,0.
    booting SCSI target 8, lun &
    Bad version Oxf3cf3ct3
    Bad version axf3cf3ct3
    Bad version axa
    Bed version axa
    Bad label
    Next>

Cheers

Hello faxmodem,

this looks to me as if you have only dumped the partition but not the whole disk including the disk label and boot block. I'm not sure about the correct command to use with dd. Maybe someone can post it here. I'm sure we can solve this issue.

Best wishes,
Andreas

Hi @faxmodem ,

here I ran into similar issues when dumping the wrong device:

here is the solution from same thread:

tldr: you need to use the "h" device to get full disk dump, like in this example

Code Select Expand

cd /BackupDisk ; dd if=/dev/rsd1h of=backup.img
My dumped disks worked perfectly fine in previous when dumped from "h" device.

Thanks !
I started over, and this time I simply hooked the scsi drive to a PC and dumped the whole drive from linux.
