When the Primary IDE Controller is set to PIO mode, the audio may be distorted or the system may startup and perform slowly. To resolve this issue, reinstall the Primary IDE Channel device driver . The Primary IDE Controller transfer mode will be reset to DMA by default.

NOTES:

  • The Primary IDE Controller can be found in Device Manager under the category IDE ATA/ATAPI controllers.
  • The Primary IDE controller may switch to PIO mode after numerous failed attempts to read a dirty or scratched CD or DVD disc. To prevent this issue from reoccurring, discard any media that cannot be read after three attempts.
