RR2720 conflict problem

[churi]

I have Supermicro X7DWA-N mother board and created a mirror OS, Windows XP professional, using its on board RAID.
Then I mounted Highpoint RR2720 and try to create RAID.

Though, after I mounted RAID card and connected mini SAS port to each HDD and boot the machine, the OS won't start.

I tried to check the boot order, though after the Intel matrix storage manager, Highpoint BIOS, it should go to BIOS if it is working usually, it turns out to a black screen with a space blinking at the very top left of the monitor.

When I plug out the mini SAS cable from the RAID card, the OS boots without problem.

I heard that BIOS flash works, so, I downloaded BIOS tool from Supermicro website and tried BIOS flash but the situation hasn't change.

I'm having a hard time following your post. Are you saying you can't get to the BIOS with the RAID card plugged in?

Hello, I have the exactly same problem.

@mfenn: it's not a problem to access the bios. The problem is to boot. Whitout any hdd plugged on the raid card highpoint 2720, everything is ok, windows runs (windows 7 for me). When I try to add hdd on the raid card, the boot stop just after the bios; instead of having the windows booting logo, I have an underscore blinking and nothing happens.

For information, I installed too my OS on a mirror (RAID 1), with the intel system integrated to the MB...

@churi, have you found a solution since your post ?

Sounds like you need to go into your BIOS and tell it to boot from the internal SATA controller instead of the HighPoint RAID card.

Hi,

I have the same issue as well. My motherboard is Supermicro X7DWA-N too and with the RocketRAID 2720 installed my machine will not post, all I get is a blank screen.

If I detach the monitor cabling the machine will boot fine, even with the card in place and hard drives attached to it via breakout cable.

I don't think it's an issue with the graphics card (I'm running a GTX 260) but with the mobo BIOS.

Sadly, this card used to allow the machine to post until I upgraded the card's BIOS (not mobo BIOS) to v1.5 due to it constantly thinking discs had failed when they were fine. I've tried reverting to the old card BIOS (I made a backup before flashing) but the problem still exists.

I'll try pulling the card and tweaking some mobo BIOS settings but if anyone can help please do.

Thanks

Try swapping the GPU and RAID card's PCIe slots.
