Boot problem of Tiger 10.4.1

I installed Tiger 10.4.1 and I can run it by booting the installation DVD and runing
rd=disk1s1 -v

in the boot: prompt before installation when I press F8.

But I need to skip this inserting the disk thing. Before I changed the boot parameters, I got an Error 22 from GRUB.

Then I went to the console and typed
fdisk -u /dev/rdisk1
fdisk -e /dev/rdisk1
print
flag 1
exit

But now, I dont get any response when I boot.

I have the OS-X installed on the primary partition of my disk, and the other partition is FAT32.

Can someone help solve my issue?
