Biggest size of config file on PIX Firewall`s Flash

[admin_2]

What is the biggest size of config file that can be saved on the FLASH ?

The best I can find on the manual regarding FLASH fs is "show flashfs" command. Here is the relevant result on 515, PIX v 5.3(2):

pix# sh flash

flash file system: version:1 magic:0x12345679

file 0: origin: 0 length:2048056

file 1: origin: 2097152 length:13251

file 2: origin: 0 length:0

file 3: origin: 8257536 length:140

According to the manual, file 1 (origin: 2097152, length: 13251)is where the config is saved.

So, let me re-state my questions:

1. The current config size is 13352 if I saved it to text file, so does it mean that the "length" value of file 1 is the current config file size ?

2. What does the "origin" value means?

Does it mean that the biggest "file 1" file size that can stored is 2Megabytes (2097152)?

Our officially supported maximum PIX configuration size is 2MB for PIX software releases v5.3(2) and later. This configuration size applies only to the PIX 525 and 535 platforms.

The maximum configuration size for the 515 and 520 is 1MB (>2MB flash is required).

"Length" is the config size.

Origin of file1 relates to the file location within the flash file system and varies depending on file0 (the operating system code).
