The above looks like the kernel.
LOAD 0x20169c 0x02800000 0x02800000 0x7dbdc6 0x7dbdc6 RWE 0
And this would be the initrd.
Could perhaps extract as such:
dd if=Compute.ebi of=Compute-kernel bs=1 skip=$[0x1400] count=$[0x20029c] dd if=Compute.ebi of=Compute-initrd bs=1 skip=$[0x20169c] count=$[0x7dbdc6]
Run file on the initrd to find out if it is compressed, but since it's 8 MB I guess it might be uncompressed.
Depending on the format of the initrd you would proceed perhaps by mounting it through the loopback device, or if it's a more modern kernel and actually initramfs instead of initrd then you would use cpio to unpack.
