Firstly, 16 is still less than 20.

Secondly, you're talking about GRUB's own device name representation. I'm talking about the way in which it scans system devices when constructing device.map. In GRUB Legacy, see lib/device.c:init_device_map; in GRUB 2, see util/i386/pc/grub-mkdevicemap.c:make_device_map. Search for "IDE disks" and you'll find that the same restriction exists in both.

I have seen the grub2 myself and it supports 16 disks, where do you see that it has the same problem?

By the way, code inspection indicates that GRUB 2 has the same problem.

GRUB only supports the first 8 IDE disks (hda to hdh on Linux). Linux supports up to hdt, i.e. 20 IDE disks. As the Ubuntu installer maintainer, I've had a report from an Ubuntu user (https://launchpad.net/bugs/94642) whose GRUB installation failed because the root filesystem is on /dev/hdl1. Is there any reason not to change "for (i = 0; i < 8; i++)" to "for (i = 0; i < 20; i++)" for IDE disks?
