[c-nsp] Weird disk0: issues

Hi all,

Recently I converted my 6509 Sup2¹s over to native.  It¹s been running
c6sup22-jk2o3sv-mz.121-27b.E4 for sometime now and now decided to take the
leap to the s222 series. The SP and RP both have 256MB RAM so I figured I am
somewhat ready to try it out.  I went ahead and upgraded RP's ROMMON to the
latest 12.2(17r)S5 ....

I have used slot0: for saving off configs and such with a 24MB PCMCIA flash
card. But with this bigger image, I am now trying to use a ATA 64MB Flash
card to boot from. Internal bootflash on the SP and RP are only 32MB and
won't hold it obviously....

But, I can't access the disk from the SP ROMMON:

System Bootstrap, Version 7.1(1)
Copyright (c) 1994-2001 by cisco Systems, Inc.
c6k_sup2 processor with 262144 Kbytes of main memory

Autoboot: failed, BOOT string is empty
rommon 1 > boot disk0:
open: read error...requested 0x4 bytes, got 0xfffffff8
trouble reading device magic number
boot: cannot open "disk0:"
boot: cannot determine first file name on device "disk0:"

And if I try boot slot0:, it just hangs ...
Also, I can¹t seem to access it from the IOS until I eject the disk and put
it back in:

Router#dir disk0:
%Error opening disk0:/ (No such device)
00:04:14: %FILESYS-SP-5-DEV: PCMCIA flash card removed from slot0
00:04:17: %FILESYS-SP-5-DEV: PCMCIA flash card inserted into slot0
Router#dir disk0:  
Directory of disk0:/

    1  -rw-    28058524  Jan 23 2009 01:07:08 +00:00

64032768 bytes total (35971072 bytes free)

NOTE:  I copied the 12.1 image down to this disk to see if it was a size
issue. I can boot all day long from bootflash:.

Router#show disk0: all
-#- --length-- ---------date/time--------- path

35971072 bytes available (28061696 bytes used)

******** ATA Flash Card Geometry/Format Info ********

   Number of Heads:       8

Is my ATA Flash card bad? I have two of them, and both of them exhibit this
same behavior.  Thoughts?
