This is what I have in my /etc/lilo.conf file:

  append = "aic7xxx=tag_info:{{2,2}}" 

And it works, `cat /proc/scsi/aic7xxx/0' shows:

Default Tag Queue Depth: 8
    Tagged Queue By Device array for aic7xxx host instance 0:
      {2,2,255,255,255,255,255,255,255,255,255,255,255,255,255,255}
    Actual queue depth per device for aic7xxx host instance 0:
      {2,2,1,1,1,1,1,1,1,1,1,1,1,1,1,1}

All this is with kernel 2.2.19. At least it shows you the correct
syntax (assuming it has not changed in 2.2.4).
