Hello,

 

I have an old system running Interactive Unix on a 15 head harddisk (4Gb).

I would like to clone this system to a 16 head harddisk because it is now difficult to find 15 head harddisks.

 

The problem is that I cannot modify the system which think it has a 15 head harddisk.

I suppose that Interactive unix use the Int13 interrupt mechanism to access the disk (am I wrong ?).

 

I wonder if there is a possibility to modify openbios so that a 16 head harddisk is used and is simulated as a 15 head harddisk by the bios ?

I would probably have to modify the drivers/ide.c file to do a conversion.

 

My questions are:

-          Can openbios boot Interactive Unix ?

-          What implementation should I use ?

 

Thanks for any help,
