Hello,

Using a 1GB CF on my system I get:

Also we can read the first sector correctly (error == 0):

   IDE read: error 00
   ide_outb (dev= 0, port= 0x1f6, val= 0xe0) : @ 0x200001f6

   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0x50
   ide_inb (dev= 0, port= 0x1f1) : @ 0x200001f1 -> 0x20
   IDE read: extd  20

But this is the *only* CF that works! Just putting another one I get:

The card is correctly identified:

   Model: Industrial CF Card Firm: ra03.00f Ser#: CIAF01000045 1
               Type: Removable Hard Disk
               Capacity: 125.0 MB = 0.1 GB (256000 x 512)

   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0x51
   IDE read: warning, device 0 not ready
   ide_outb (dev= 0, port= 0x1f7, val= 0xe5) : @ 0x200001f7
   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0xd1

   ide_outb (dev= 0, port= 0x1f5, val= 0x00) : @ 0x200001f5
   ide_outb (dev= 0, port= 0x1f6, val= 0xe0) : @ 0x200001f6
   ide_outb (dev= 0, port= 0x1f7, val= 0x20) : @ 0x200001f7
   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0xd1
   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0x51
   Error (no IRQ) dev 0 blk 0: status 0x51
   ide_inb (dev= 0, port= 0x1f1) : @ 0x200001f1 -> 0x10

But the ide_read() returns error!

   IDE read: error 10

Using the REQUEST_SENSE command I get:

   ide_outb (dev= 0, port= 0x1f6, val= 0xe0) : @ 0x200001f6
   ide_outb (dev= 0, port= 0x1f7, val= 0x03) : @ 0x200001f7
   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0xd0
   ide_inb (dev= 0, port= 0x1f7) : @ 0x200001f7 -> 0x50
   ide_inb (dev= 0, port= 0x1f1) : @ 0x200001f1 -> 0x1f
   IDE read: extd  1f

Which means: Data Transfer Error / Aborted Command

Any suggestions?

Rodolfo
