Hello to all,
  
  I have a ATA33 motherboard and a IBM ATA100 disk.
  
  My questions/doubts are:
  
  	- if the motherboard controler is ATA33 then the maximum ATA that IBM 
  disk can reach is ATA33, right?
  
  	- if the above question is true, then why  a message like "ata0-master: 
  DMA limited to UDMA33, non-ATA66 compliant cable" knowing that the 
  motherboard controller is ATA33 and has been probed by kernel?
  
  
Thanks very much,
