|
|
|
- * insmod ide-cd ignore='hda hdb'
|
|
|

|
|
|
- * for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers

|
|
|
- * They will disappear later when I get the time to
|
|
|
- * do it cleanly.
|
|
|
- * - Minimize the TOC reading - only do it when we

|
|
|
- * Uniform layer.

|
|
- * - Added partition based multisession handling.
|
|
|
- * - Mode sense and mode select moved to the
|
|
|
- * Uniform layer.

|
|
|
- * correctly sensing a disc change.

|
|
- * - Rearranged some code
|
|
|
- * - Use extended sense on drives that support it for
|
|
|
- * correctly reporting tray status -- from
