Thank you for your help. In answer to your questions:
Can you "see" the PCI IDE controller at this address? What's the
output of:
=> md.b e80001f0 10
I believe not because => md.b e8000000 10 e8000000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................
What's the output of: => pci long
=> pci long Scanning PCI devices on bus 0

I suppose that the oxFF bytes are not correct for the contents of the ide controller registers. What should I look for?
I used 0xE8000000 (apparently incorrectly) because it was reported in the following messages when initializing with the PPBBoot firmware: PCI_Scan:Device 4 is present Bus Func 2000 ClassCode 101 IDE device found: PCI_Config_Device:Read Base Addr Reg 0 = 0x000001f1 ***PCI I/O space = 0x10 bytes 0 IDE-Just Set CFG_ATA_BASE_ADDR to e8000000^M PCI_Config_Device:Read Base Addr Reg 1 = 0x000003f5 ***PCI I/O space = 0x4 bytes 10 PCI_Config_Device:Read Base Addr Reg 2 = 0x00000171 ***PCI I/O space = 0x10 bytes 20 PCI_Config_Device:Read Base Addr Reg 3 = 0x00000375 ***PCI I/O space = 0x4 bytes 30 PCI_Config_Device:Read Base Addr Reg 4 = 0xffffffc1 ***PCI I/O space = 0x40 bytes 40 PCI_Config_Device:Read Base Addr Reg 5 = 0xfffe0000 ***PCI Memory space = 0x20000 bytes Hardcode address e80001f0
PS: Please use a subject next time!
