AMI BIOS FOR 5170

AMI released a BIOS specifically for 8 MHz 5170's. From memory, it was used when the IBM hard/floppy controller was replaced by a third party board (which causes a "601-Diskette error" error). The BIOS is dated 04/30/89. This BIOS has built-in CMOS setup functionality, a user defined hard drive type (type 47), and diagnostics (includes hard disk format). This BIOS will no doubt run in all 5170's.
