Sadly, I've gotten no-where with this yet.
I installed CentOS onto another server's (I freed up an HP Prolaint DL360 with the same drive bays) drive, but it doesn't bootup the drive. I think it gives an error, but I can't tell. I also can't see it requesting an IP from the DHCP server, nor can I ping the hard coded IP (i.e. I first setup the installation with DHCP, then changed it to a hard coded IP).
I know this sounds funny, but I don't have a null-modem cable. Anywhere. I know we had one a few years ago but can't find it.
The PCI graphics card that I could get my hands on is too low so the VGA port is below the chassis. Short from ripping the motherboard out, it won't work. But, while googleing to see if I could fit a PCI graphics card in, I also found some posts where people say the PCI card's burnt some lanes on the PCI-X port, so I don't want to try this and find out it might blow a track.
No one that I could get open right now has a C2T cable in stock.
