+ *  Version 0.01	Initial version, hacked out of ide.c,

+ *			This will get cleaned up in a subsequent release.
+ *
+ *  Version 0.02	now configs/compiles separate from ide.c  -ml
+ *  Version 0.03	enhanced auto-tune, fix display bug
+ *  Version 0.05	replace sti() with restore_flags()  -ml
+ *			add detection of possible race condition  -ml

+ * To set the speed according to the abilities of the hardware there must be a

+ * #define UMC_DRIVE0 11

+ * the results from the DOS speed test program supplied from UMC. 11 is the 
+ * highest speed (about PIO mode 3)
