- * To enable UMC8672 support there must a lilo line like
- * append="hd=umc8672"...
- * To set the speed according to the abilities of the hardware there must be a
- * line like
- * #define UMC_DRIVE0 11
- * in the beginning of the driver, which sets the speed of drive 0 to 11 (there
- * are some lines present). 0 - 11 are allowed speed values. These values are
- * the results from the DOS speed test programm supplied from UMC. 11 is the 
- * highest speed (about PIO mode 3)
