ML350 G3 on-board SCSI

Why does the SCSI BIOS always report Async SCSI transfers were negotiated with the disk backplane or a tape device connected?

Re: ML350 G3 on-board SCSI

Could you report the exact message and where exactly it occurs in the bootup sequence?

Re: ML350 G3 on-board SCSI

The HP's version of the Adaptec BIOS does not support Synchronous mode. Once the driver loads in the OS it will operate at its maximum speed.
There’s your problem!!! This thing is set to EVIL!

Re: ML350 G3 on-board SCSI

Vijay,
One more question.
We have our own OS and driver built using Adaptec's CHIM (common hardware interface module) we correctly identify the on-board host in PCI space but the first call into the CHIM returns an unsupported host adapter type. Is there somthing unique about HP'S implementation/driver? Our driver works properly with Adaptec 19160/29160/39160 host adapters and various on-board configurations from other vendors.
