i386 problems

Hi
I'm trying to get RedBoot working on an ordinary i386 desktop system.
I followed the instructions in the eCos book in order to build an i386
floppy image but am having a few problems with it. It doesn't seem to
detect the extended memory. It only detects the base memory. I tried
the image on three different PCs, same result.
RAM: 0x00000000-0x000A0000, 0x0008A4B0-0x000A0000 available
Anyhoo, I tried loading a stock linux kernel (bzImage) over TFTP which
went alright. It seemed. RedBoot said it had loaded the kernel to
address 0x800000. However when the script got to the 'go 0x800000' in
my script it froze. I think it freezes in this call:
HAL_THREAD_SWITCH_CONTEXT(&go_saved_context, &workspace_end);
Another problem is that keyboard doesn't work. It's a USB keyboard
connected to the PS/2 port with a USB/PS2 converter.
I've googled, searched the list archives and gone through the book and
doc to no avail. Any help on these issues will be much appreciated.
