You can split the upgrade file into chunks and use 'download' on each chunk. Here's me doing it about 6 years ago: https://blog.differentpla.net/blog/2019/03/29/empeg-msata/#extract-the-upgrade-file-parts

Caution: this was with the empeg's disk attached to my Linux PC, but with the empeg attached over serial. You want just the 'upgrader' and 'download' steps.
