root(hd1,) work only if entered at boot time

Hi!

In short :

grub ( run from boot block ) accepts ( via manual edit ) both
"root(hd1,0)" and "root (hd1,0)" ( space between "root" and "(hd1,0)" ),
but in /boot/grub/grub.conf only "root (hd1,0)" is accepted, while
"root(hd1,0)" is silently dropped ( boot grub, edit the entry and
see that the "root(hd1,0)" line is missing.

Long story :

I added a new disk in my system ( hdd ) and added a boot entry for it
in grub.conf on my Psyche ( RH 8.0 ) system :
( the last entry for phoebe BETA is new )

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this
file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,5)
#          kernel /boot/vmlinuz-version ro root=/dev/hdc6
#          initrd /boot/initrd-version.img
#boot=/dev/hdc
default=2
timeout=2
splashimage=(hd0,5)/boot/grub/splash.xpm.gz
title Red Hat Linux (2.4.18-18.8.0)
        root (hd0,5)
        kernel /boot/vmlinuz-2.4.18-18.8.0 ro root=LABEL=/ hda=ide-scsi
        initrd /boot/initrd-2.4.18-18.8.0.img
title Red Hat Linux (2.4.18-14)
        root (hd0,5)
        kernel /boot/vmlinuz-2.4.18-14 ro root=LABEL=/ hda=ide-scsi
        initrd /boot/initrd-2.4.18-14.img
title Windows 2000 Pro
        rootnoverify (hd0,0)
        chainloader +1
title Red Hat Linux 8.0.93 phoebe BETA
        root(hd1,0)
        kernel /boot/vmlinuz-2.4.20-2.21 ro root=LABEL=root_93
hda=ide-scsi
        initrd /boot/initrd-2.4.20-2.21.img


The entry is correct, but on boot it complains error 15 : file not
found.

It turns out ( select the entry in boot menu, press e ) that the
"root(hd1,0)"
line got lost.
If I add it manually ( 'O' , 'e' , type "root(hd1,0)" , ENTER , 'b' ), 
then it boots without a problem.

grub is  grub-0.92-7
I upgraded it to grub-0.93-2 ( from phoebe2 CD ) , run "grub-install
/dev/hdc"
and it still behaves the same.

Solution :
Replace the "root(hd1,0)" line with "root (hd1,0)" .

How to syntax check grub.conf ?
