I checked these and made a couple of changes but to no avail. Then I added the following lines to my board configuration file that I copied from the tqm8xx.h file: /* * Definitions for IDE0 Interface */ #define IDE0_BASE_OFFSET 0 #define IDE0_DATA_REG_OFFSET (PCMCIA_MEM_SIZE + 0x320) #define IDE0_ERROR_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 1) #define IDE0_NSECTOR_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 2) #define IDE0_SECTOR_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 3) #define IDE0_LCYL_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 4) #define IDE0_HCYL_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 5) #define IDE0_SELECT_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 6) #define IDE0_STATUS_REG_OFFSET (2 * PCMCIA_MEM_SIZE + 0x320 + 7) #define IDE0_CONTROL_REG_OFFSET 0x0106 #define IDE0_IRQ_REG_OFFSET 0x000A /* not used */ #define IDE0_INTERRUPT 13 /* = SIU_LEVEL6 */ This was the clincher, the defined values I had did not have the 0x320 offsets factored in. I also had the IDE0_INTERRUPT set to the wrong value. Now with these changes all is well. I was able to successfully mount the partition and see my files.
