Huh? default is 0, so it will go against the first title, not the last.
Wait - I haven't been following this over the weekend, so I can't tell if
someone's email has run the lines together. The first entry has to be
>> title CentOS (2.6.18-194.17.1.el5)
>> root (hd0,0)
>> kernel /vmlinuz-2.6.18-194.17.1.el5 ro root=/dev/md1
>> initrd /initrd-2.6.18-194.17.1.el5.img
with the next "title" on the next line.
