LILO problem after changing to Adaptec 2940U

[Chris Evans]

My problem is that booting from the hard disc gets LI but not LO, 
i.e. LILO isn't mounting linux.  Two people (many thanks) 
suggested I instruct lilo to use linear addressing either by using the 
lilo -l option or putting "linear" into /etc/lilo.conf.  This sounds very
promising but I think the way that changing from a dawicontrol (ncr) 
to the Adaptec 2940U changes the perceived geometry is more 
serious than this.  After booting in rescue mode from the 
resc1440.bin floppy lilo (with or without linear mode) returns:

Device 0x0800: Invalid partition table, 1st entry
     3D address:   1/1/0 (32)
     Linear address: 30/1/0 (61)

-v shows it's reading /dev/sda1 (correct) for that error message so I 
seem to be caught in a bind that the resc floppy can mount the 
drive but the geometry has been changed so fundamentally I can't 
rewrite the bootable version of linux in a way that lilo will use.

I'm back to you all again.  Any suggestions?  (The old controller is 
happily running another machine miles away and I can't find 
another like it around and I'd hate to ditch the money I spent on the 
Adaptec so ... yes, ... I too would like to do the sensible thing but 
can't !!)

TIA,

Chris
