Solve the Problem of abnormal PCI device on IBM x346
IBM x346 server, because many PCI devices on the machine have Rom space limited by kb,
The message "1801 PCI device Resource Allocation failure" is displayed at startup.
For more information about the cause and solution of this message, see the following URL:

The Rom space of the Intel Platform System is limited to kb, and the current requirements of servers are becoming more and more complex. As a result, more and more devices are integrated or installed on servers, and many devices need
The system ROM resources are initialized or work properly, which causes the ROM space shortage and the 1801 PCI device Resource
The error message of allocation failure causes some devices to fail to work normally.
To solve the 1801 error, try the following methods:
1. Disable unused devices (such as the SCSI controller integrated with the motherboard) or functions (such as the PXE/DHCP function of the integrated Nic), and release Rom space for other devices.
2. The serveraid 7 k card can be added on the x236 or x346 models to free up approximately 17kb of Rom space.
3. Add the rsa ii slimline card to the server and disable the ROM execution function of some devices through the advanced settings of the card.
4. Change the start priority of the PCI device in the BIOS.
The following are the known causes and solutions for 1801 errors on some IBM servers:
