cards. Since the firmware is hard coded into the kernel, I've made it a kernel option (WI_SYMBOL_FIRMWARE). Note: This only downloads into the RAM of these cards. It doesn't download into FLASH, and is somewhat limited. There needs to be a better way to deal, but this works for now. My Symbol LA4132 CF card works now. Obtained from: NetBSD
