Caution, this command may crash your system, be prepared for a hang or a reboot. Reading the ISA whole at 640k->1MB can cause some really strange hardware actions to occur that FreeBSD is not prepared to handle. Especially true if you have memory mapped cards with register banks in that address range. If your going to do the above make sure you are in single user mode, and if it does not find an NCR string that is not an absolute indicator that you don't have an NCR bios, as some MB's map out the bios if it returns saying it found no devices. If the NCR string does show up, you defanitly have the NCR BIOS, but the opposite is not always true. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
