How do retrive data from crashed UnixWare 7 disk?

While I am playing with "dcu" I have removed few entries [SCSI inteface at IRQ 11, Network card at IRQ 10, Custom software at IRQ 7) from the "dcu". After saving this setting I am able to reboot the system. "gives the error vfs mount: / not found".
1. I have not partioned the disk of 2GB while installing.
2. I tried unix.old and unix.safe but not booting.(same error repeates)
3. I tried putting it as secondary disk and tried to mount. But not able to mount the device. [mount -F vxfs /dev/hda/hda1/ /mnt]
How do I mount secondary disk in this case.
4. Can I get a basic "unix" kernel of UnixWare 7 which will fit in to 1.44MB floppy disk.
5. Can I reinstall the OS without damaging my data on the same disk.
6. What are the other alternatives.

Did you try boting with Unixware CD? If not try this. The procedure can be found under ww.sco.com/ta

Hi Mohan,
 The TA105315/6 talks about UW 2. And UW7 TA refers to the above TA# of UW2. But UW 7 does not give the option of NON DESTRUCTIVE installation of the OS. How do I install without spoiling the data?

You said you tried to put it as second disk and mount this HDD on to the 1st HDD(another/ new) with working Unixware. Did you config. the second HDD using "diskadd [-F s5dm]"? Otherwise you can't access the 2nd HDD.
If you don't have any emergency_boot media buthave installation boot floppies and CD-ROM, then it is possible. The procedure is again available in TA#109264
