I recently upgraded our PIX515 firewall from Version 7.2.2 to 7.2.4 and I wanted to verify the MD5 hash for the downloaded IOS. However the hash generated on the PIX using the verify command does not match the hash published on the cisco download website. Published hash is f2f6b88ea1b4a0b33045b3b18d0fb852, generated hash is fdcd.... . I checked the 7.2.2 MD5 on a firewall I haven't upgraded yet and that doesn't match either. Am I missing something ?
OK, so you downloaded an interim release - 7.2.4(30), instead of the main release of 7.2.4.
The checksum for 7.2.4(30) is correct and matches what you advised earlier: fdcd3a9d884baf0ec0aad78048f0e441

Hope that clarifies the confusion.
