The BIOS call that boot.S is using (int 0x14) only supports a maximum speed of 9600. To get speeds greater that 9600, it needs to do the I/O itself. There used to be a version floating around that did this. I have a extemely modified version that uses this method. If you can't find a version that does this, let mw know and I'll see if I can cleanup what I have.
