[arch-general] rescue shell in GRUB2

Hello, on GRUB2 wiki, I see in case of serious problems, I am dropped to a rescue shell. At one time, I shall type :

insmod(hd1,1) /grub/normal.mod **my /boot is on separate partition on /dev/sdb1

When I look inside my /boot/grub folder, I can see the file normal.mod is inside /i386-pc folder. So why not instead type :

insmod(hd1,1) /grub/i386-pc/normal.mod

TY **
