I believe the MBR is the first 512 bytes of the SD card, the first
partition contains the kernel, the second partition contains the initial
ramdisk, and the third partition is where the linux file system lives.

By default the kernel and initial ramdisk is loaded from the onboard
flash, the tsbootrom-update command you ran modifies the preboot in the
e2 so the kernel and initial ramdisk is loaded from the SD card. We
didn't intend people to do this on a TS-7400. The reason being the
initial ramdisk on the SD card contains functionality for the TS-7300
FPGA. If you would like to load the initial ramdisk and kernel from the
SD card, then you would need to copy the initial ramdisk and kernel from
the onboard flash to the SD card using the mtdcopy utility.

You can download the fastboot SD image here
ftp://ftp.embeddedarm.com/ts-arm-linux-cd/binaries/ts-images/fastboot-7300-sdcard-7-6-2006.dd.bz2
You can read the SD card filesystem from this image, you can read the
MBR, initial ramdisk, and kernel from the onboard flash.
