The bios on the board is a PMC 49FL004t-33jce. Found a data sheet for that, and it does use the LPC. I'm looking at the SST parts right now. Googling for PRI_BOOT_LOC brings me right back to the list. :) Looks like this is shown with flash rom? Guess it's time to fire up svn and grab some code. This stuff has come a long way since the 27cxxx chips. :)

Ok, the board has a plcc 32 rom socket on it, so it looks like I'm limited to 8mbit without constructive surgery and adding address lines.
I can't quite read the part number of the PMC flash device on any of the on-line pictures of the Kino board. My guess is that it is an LPC/FWH ROM, not a parallel ROM. ROMs on LPC have 4 muxed address/data lines. You don't need to worry about adding address wires, all memory/FWH reads/writes are 32-bit addressed.
Looks like a LB/Filo setup booting off parallel compact flash. Any good sources for spare flash roms? Digikey?
Search Mouser for "LPC", and look at the memory ICs category. I see a couple of 4 and 8Mb parts in stock. You can use the 16Mb parts, if you can find them to buy. I can't find any on-line, but a distributor may be able to get them (SST49LF016C {FWH} or SST49LF160C {LPC})
Make sure you purchase the correct version of ROM for how your board is strapped. Boot your board, and check the PRI_BOOT_LOC field to know where 5536 is booting from. (the PMC part in the pictures of the Kino board can work in either mode)
