Other that JTAG, the only way to upgrade the firmware is to boot up far
enoug that you can run the "flashwrite" utility.  It has been a long while
but I suspect you will want the 990121 kernel (or earlier)

You can get this kernel to boot either via netboot (ethernet), by serial
download, or by getting it on the hard drive somehow (eg. other PC).
