Default Server 9.10 Grub not installed

Installed 9.10 server with RAID1 + LVM:
Code:
$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] 
md1 : active raid1 sdb2[1] sda2[0]
      311588608 blocks [2/2] [UU]
      
md0 : active raid1 sda1[0] sdb1[1]
      979840 blocks [2/2] [UU]
      
unused devices: <none>
Set md0 as /boot and md1 as LVM thus:
Code:
~$ df

LVM volume 1 of the (single) volume group is 5 GB swap space.

fdisk shows something:
Code:
~$ sudo fdisk -l

2 heads, 4 sectors/track, 244960 cylinders
Units = cylinders of 8 * 512 = 4096 bytes
Disk identifier: 0x00000000

Disk /dev/md0 doesn't contain a valid partition table

Disk /dev/md1: 319.1 GB, 319066734592 bytes
2 heads, 4 sectors/track, 77897152 cylinders
Units = cylinders of 8 * 512 = 4096 bytes
Disk identifier: 0x00000000

Disk /dev/md1 doesn't contain a valid partition table
Neither MD devices contain a valid partition table -- is that normal?

When the system boots, GRUB does not display at all -- it just boots. There is no menu.lst file in /boot/grub. And, grub is not installed as in:
Code:
$ grub
The program 'grub' is currently not installed.  You can install it by typing:
sudo apt-get install grub
grub: command not found
My main concern is will the system still boot if /dev/sda becomes non-operational? What happened to grub with 9.10?

Thanks

Default

OK... Somehow I missed out on Grub 2.0 as the 9.10 default. I guess I'll figure out how to get to memtest if I need it. And I'll just pull the plug on sda to see if it boots off of sdb alone....
