That sounds like the microcode bits were prepended to the initrd file.

If that is the case then it's hard to inspect the rest of the contents of that
file, at least in the usual way.

I don't normally use an initramfs but I had one with a gentoo install and I
found the same thing. Gentoo's initramfs tool (i forget what it called now)
created a huge initramfs but I was only able to see the intel-ucode bits of it
when I tried to look inside of it.

It must have contained a lot of modules but it did boot up just fine.
