Memory and Booting question about SUP720

What is the different between sup-bootflash and sup-bootdisk on sup720??
There is one file in sup-bootflash and sup-bootdisk. File name is cr1. 
I teseted that deleting  one file from sup-bootdisk. 
After that, i check sup-bootflash directory and I relized there'no 'cr1' file
It seems to me same. Am I right?

One more question

RP rommon mode, why sup720 doesn't show me the file directory?
Cat6k-Sup720/RP platform with 524288 Kbytes of main memory

rommon 1 > dir bootflash:
         File size           Checksum   File name
rommon 2 > dir bootdisk:
bad device name (Device not supported) 
usage: dir <device>
rommon 3 > dir sup-bootdisk:
bad device name (Device not supported) 
usage: dir <device>
rommon 4 > dir sup-bootflash:
bad device name (Device not supported) 
usage: dir <device>
rommon 5 > 

 //  I don't have disk0 and disk1 //


but i can see when SUP720 is on SP rommon mode, it shows the files. 

In this situation, How can i specify boot file ?

Earlier sup720s had bootflash (64KB?), which was too small to contain later IOS images.  So, Cisco provided a upgrade kit that provided a larger "bootdisk" that took the place of bootflash, they also map the latter (name) into the former.  (Also, newer sup720s come with bootdisk too.)

Besides bootflash and bootdisk being determined by which is physically on the sup card, I believe processor boot ROM version images come into play.

Your other question about SP vs. RP boots, is also a bit of a muddle.  Original setups (old hybrid mode) has SP boot for L2 and RP boot for L3, now the normal (native mode) manages both, and appears to hide (or rename, or make inaccessible?) some SP flash when IOS is controlling device.  So, when you access the two different processors, there can be differences in what they "see".  I.e. there's a bootflash for both, but the newer native mode IOS images don't use SP bootflash, I believe.

Thank you for your reply. 

Thank you for your reply. 

 

Can I ask you one more question? Can you explain what exactly miniIOS is ?

I saw doc it says config-register 0x2101 is miniIOS mode. 

What is miniIOS? Rreloading with 0x2101, system goes into rommon. looks like normal rommon mode. 

Can you help me ?

Thank you in advance : )

I don't recall miniIOS (or RXBOOT) being supported on the 6500 series.

7200s, I recall, used to support a special IOS to be loaded into their bootflash.

See page 2's "Types of Images" in http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sys-image-mgmt/configuration/15-mt/sysimgmgmt-15-mt-book/sysimgmgmt-imgs.pdf
