Cannot boot from Intel on-board controller if Highpoint card has any disks

[Cford]

When I try to boot (into Windows) from a disk plugged into the Intel controller on my Gigabyte EP45C-DS3R motherboard, with any other disk connected to the Highpoint 1740 card, (regardess of what is on that disk), the computer gets to the stage where it should load an operating system and just gives a flashing cursor on a black screen instead. There is no such problem if the Highpoint card is empty at that stage, and then hot-swap drives are plugged in immediately after the OS has started booting.
Also, I cannot get into the motherboard BIOS while the Highpoint card has any drives in it! No amount of pressing keys at the right time will achieve this, so the Highpoint BIOS seems to be blocking those keys/request? In the motherboard BIOS I have tried any settings associated with boot order.
Any ideas, please? Thanks, Chris.

Motherboard Model: Gigabyte EP45C-DS3R
System BIOS version: ep4cds3r.f5 ?
System memory size: 4GB
Highpoint BIOS/Firmware Version: 2.0-102307
Highpoint Driver version: 2.0.7.1023
Operating System: Windows Server 2003
On-board Intel ICH8R SATA RAID controller

I had a similar issue with the HPT controller that I am using and I was able to correct it by disabling 'Reallocate EBDA' in the HPT BIOS. I'm not sure about your particular model but mine allows you to change the settings with the Flash Utility that HighPoint provides.

Did this info from FlyingHorse help any?

When setting things in the BIOS, are you setting "Hard Disk Boot Priority" to the drive you are wanting to use (If possible)?

Thanks! I've just tried this and it worked. It had no effect when I used the Windows hptflash utility and rebooted, but when I set it from a DOS boot disk, using load.exe /C biosfilename, it worked fine and the system booted with all disks present. [I had already checked the boot order in the BIOS.]
