When i run the following command dir slavesup-bootdisk:
Directory of slavesup-bootdisk:/
1 -rw- 47578116 Nov 4 2007 18:51:18 -05:00 s3223-ipservices_wan-mz.122-18.SXF11.bin

as per me directory 1 and 2 show -- Current IOS on the switch
You basically have 3 filesystem formats with a SUP -
Here are the definitions of each:
disk0: = CF slot on the SUP for an external flash card
sup-bootdisk: = on-board flash for the SP (switch processor) of the SUP
bootflash: = on-board flash for the RP (route processor) of the SUP
These are 3 distinct file systems. When a SUP crashes, we should generate a crash file from both the SP (stored in sup-bootdisk:) and the RP (stored in bootflash:). When you store IOS images, you want to store them in either the external CF slot (disk0:, disk1:, etc.) or sup-bootdisk: as these are the file systems the SP can see when it boots up (the SP will boot first in a SUP boot-cycle). The SP cannot see the bootflash: on the RP when booting. The 'slave' designations are simply added on to indicate that the file systems are for the standby SUP.
Let me know if that clears it up.
