  Hi!

  (Sorry for my poor english)
  
  Hardware: MB Acorp SiS22, HDD Caviar 22100(prim. mast.), CDROM
  Toshiba  XM-6702B(prim. slav.)
  OS: FreeBSD-4.1
  
  I have trouble with my booting up my computer. I see these messages:

  ad0: 2014MB <WDC AC22100L> [4092/16/63] at ata0-master using UDMA33
  acd0: CDROM <TOSHIBA CDROM XM-6702B> at ata0-master using PIO4

  ata0-master: timeout waiting for command=ef s=00 e=60
  ad0: trying fallback to PIO mode
  ata0: reseting devices ..  device dissapeared! 1 done
<continue booting>

  When I remove CD-ROM from machine, OS can't boot:

  Mounting root from ufs: /dev/ad0s1a

  ad0: error exiting command
  ad0: reading primary paritition table: error reading fsbn 0
  Root mount failed: 5
  Mounting root from ufs:wd0s1a

  What's wrong?
