scsi hdd can't be seen when installed a ati rage 128 on pci slot
how ca i solve this problem ? i'm installing a new viveo card on my
ibm p4 1.7 with scsi hdd on it the scsi controller is installed on pci slot 5 and and did install my video card on slot 1 or 2 but when i reboot my pc i get message system halted operating system cannot load |

Hi,
You need to give the EXACT error message and describe the screen where you see it. "System Halted" and "Cannot load operating system" are two different things. "System Halted" is usually a BIOS message (not related to SCSI) "Cannot load operating system" (or similar) is after it's found the disk controller but can't make sense of the boot sector. You also need to give the exact make model of your SCSI controller, Video card, mainbaord, o/s etc. It's possible the video card hardware interrupt has conflicted with the SCSI controller, but this is extremely rare on PCI with modern kit. Check also your BIOS defaults in case you have forced any IRQs. efos wrote: how ca i solve this problem ? i'm installing a new viveo card on my ibm p4 1.7 with scsi hdd on it the scsi controller is installed on pci slot 5 and and did install my video card on slot 1 or 2 but when i reboot my pc i get message system halted operating system cannot load -- Gerry_uk |

On a desktop motherboard, the memory area in question might be limited to 128KB. Things that share this memory a 1) video card BIOS (there is a BIOS chip on the video card) 2) storage card BIOS (there is a BIOS chip on the SCSi controller) 3) network bootable networking card (PXE) When a computer has a number of devices like that, the computer can run out of the type of low memory needed. It is a first come first serve system, so the add-in BIOS modules get their memory allocation, in the order of enumeration. What it can mean, is a storage card whose BIOS used to load (like a SCSI card), suddenly can no longer load. And for the SCSI card, if the SCSI BIOS does not load, the computer cannot boot from the SCSI card. This quotation from Tyan Tech Support is where I first learned of this: http://forums.2cpu.com/showthread.ph...ng+sc si+bios Q: Why doesn't the BIOS (Option ROM) for my PCI device show during boot up? A: The cause of the problem is that in order to be PC Compatible, the Option Rom space is limited to 128K. This is true for any motherboard with PC compatible BIOS'. In the common configurations, a newer AGP card (such as any GeForce4) will require 64K of Option Rom space, so you have only 64K of Option Rom space left to work with for other devices. Many SCSI, NIC (w/ PXE), IDE Raid and etc., can easily use another 40 to 64K of Option Rom space for their needs. By design the Option Rom should shrink down to a smaller run time code after the initialization code has run. For example, some Adaptec cards will require 32K to initialize. Then they shrink down to 12K at run time; whereas some GeForce4 cards require 64K to initialize and never release to a smaller amount. Please check with the device manufacturer for the latest firmware upgrade or ask if they have a smaller Option Rom available. Again this is a limitation of the PC compatible specification and not a failure of the motherboard BIOS itself. The normal solution to this, is to either disable any unneeded option ROMs. (For example, if the motherboard network interface supports PXE, disable the network boot ROM in the BIOS. If you have three SCSI cards, disable the BIOS on the two you are not booting from.) Or, change the slots that the cards are plugged into. For example, if the SCSI card is plugged into PCI slot 1 (the PCI slot closest to the processor), then the SCSI card gets enumerated before any other PCI cards. It could be, that it will result in the other PCI cards, not being able to use their Option ROM, but it may allow the computer to boot. HTH, Paul |
