I have built a linux image with GRUB2 as its boot loader and written it on an IDE hard disk. When I put it in a computer with Intel cpu, it works fine. But putting it in an AMD cpu computer, it even fails to detect the HDD and raises the following error:
Not found any [active partition] in HDD DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER
Also I have tested with grub-legacy, it again works fine. SO it seems that GRUB 1.9* is not compatible with maybe old AMD CPUs.
Please note that the PC under test spec is as follows:
CPU TYPE: AMD-K6(tm)-2 CPU-CLOCK: 300 Pri- Master Disk: LBA, UDMA 33, 1040MB
Also note that I have tested in two systems, (two INTEL and two AMD), and still same result.
