ENHANCEMENTS: 
- Adds setup option to the Advanced-->Chipset/Memory menu to disable PCI 
segmentation. This is a workaround for Linux kernels that do not correctly 
support PCI segmentation. 
- Optimizes memory mapped I/O (MMIO) memory mapping to increase available 
system memory. 
- Enables a second I/O Advanced Programmable Interrupt Controller (IOAPIC). 
This prevents the PCI Express slots from sharing an interrupt.

FIXES: 
- Fixes issue where a workstation configured with an ARC-1110 PCI-X SATA Raid 
Card stops responding (hangs) during Power-On Self-Test (POST). 
- Fixes issue where a workstation configured with an PURE P1800 PCI Express 
Card stops responding (hangs) during POST. 
- Fixes security issue with Power-On password and power button override during 
a warm restart (reboot). 
- Fixes issue where it was not possible to correctly specify certain PCI 
options. 
- Fixes issue where a workstation configured with an Adaptec 2120S RAID card 
stops responding (hangs) during Post.
