Help Booting Live Disk

Hello everyone,
Not sure if I should be in here or in the Bugs section, but here's the layout.

1)Have a server that has a raid 5 that went down, it has 4 hard drives total.
2) SuperMicro Server (if that makes any difference)
CPU Type: Intel(R) Xeon (TM) CPU 3.00GHz (It'd Dual Core)
CPU Speed: 3.00 GHz
2GB of Ram
1 CD / DVD drive
4 160GB HDs in a Raid 5 setup

3)
What happens during boot (regardless of live or vga):
In both cases the system will lock up before actually booting.

*Starting configure network device security [ OK ]
*Starting Mount network filesystems [ OK ]
*Starting Failsafe Boot Delay [ OK ]
*Starting Bridge socket events into upstart [ OK ]
*Stopping Mount network filesystems [ OK ]
*Starting configure network device security [ OK ]
*Starting configure network device [ OK ]

4)I've tried multiple linux versions and so far none have been able to really boot into the system yet. Am running a Memtest, but usually a system would yell at me that something is wrong with the memory.

5)Any help in terms of booting into this thing with the live disk would be super helpful.
Thanks ahead of time.

Since this is a problem with

Since this is a problem with multiple OSes, I would troubleshoot hardware. Can you boot with the drives unplugged? A bad SATA/Raid controller is a likely culprit for lockups at boot time.

You can always boot from another box and plug the drives in using whichever interface you want and then assemble the array by hand.
