På min Linux box (AMD K6-300 MHz, Aopen AX59PRO, IBM Deskstar 6,4Gb UDMA) er
forskellen på 16 bit mode og 32bit lille men synlig (og konsitent):

   I/O support  =  0 (default 16-bit)
   Timing buffered disk reads:  32 MB in  2.92 seconds =10.96 MB/sec

   I/O support  =  3 (32-bit w/sync)
   Timing buffered disk reads:  32 MB in  2.82 seconds =11.35 MB/sec
