MS-7207 M-ATX Mainboard a technique that DRAM itself predicts the address of the next memory location to be accessed after the first address is accessed. To use the feature, you need to define the burst length, which is the actual length of burst plus the starting address and allows internal address counter to properly generate the next memory location. The bigger the size, the faster the DRAM performance. Setting options: [8 Beats], [4 Beats] and [2 Beats]. Hardware M emory Hole In order to improve performance, certain space in memory can be reserved for ISA peripherals. This memory must be mapped into the memory space below 16MB. W hen this area is reserved, it cannot be cached. Settings: [Disabled], [15MB-16MB]. Hyper Transport Configuration The following items are used for setting the frequency and the linkwidth from CPU to North Bridge and from North Bridge to South Bridge. CPU to NB Frequemcy: NB to SB Frequemcy: CPU to NB LinkWidth: NB to SB LinkWidth: 200/400/600/800/1000 MHz 200/400/600/800/1000 MHz 8↓8↑/16↓16↑ 4↓4↑/8↓8↑/16↓16↑ Flash Protect This function protects the BIOS from accidental corruption by unauthorized users or computer viruses. W hen enabled, the BIOS data cannot be changed when attempting to update the BIOS with a Flash utility. To successfully update the BIOS, you will need to disable this Flash Protection function. Setting options: [Enabled], [Disabled]. Primary Graphics Adapter This setting specifies which VGA card is your primary graphics adapter. Setting options are: [PCI Express] The system initializes the installed PCI Express card first. If an PCI Express card is not available, it will initialize the onboard VGA card. [Onboard] The system initializes the onboard VGA card first. OnChip and PCIe VGA selection This setting allows you to enable both OnChip and PCIe VGA, or enable PCIe VGA only. Setting options: [Disbale Onchip VGA if have PCIe VGA], [Both exist and OnChip VGA by frame buffer select]. OnChip VGA Frame Buffer Size Frame Buffer is the video memory that stores data for video display (frame). This field is used to determine the memory size for Frame Buffer. Larger frame buffer size increases video performance. Setting options: [Disabled], [16MB], [32MB], [64MB], [128MB]. RGB/TV Display This item allows you to select an display device to display. Setting options: [Auto], [RGB], [TV]. 3-12

a technique that DRAM itself predicts the address of the next memory location to be
accessed after the first address is accessed. To use the feature, you need to define
the burst length, which is the actual length of burst plus the starting address and
allows internal address counter to properly generate the next memory location.
The
bigger the size, the faster the DRAM performance.
Setting options: [8 Beats], [4
Beats] and [2 Beats].
Hardware Memory Hole
In order to improve performance, certain space in memory can be reserved for ISA
peripherals. This memory must be mapped into the memory space below 16MB.
When this area is reserved, it cannot be cached. Settings: [Disabled], [15MB-16MB].
Hyper Transport Configuration
The following items are used for setting the frequency and the linkwidth from CPU to
North Bridge and from North Bridge to South Bridge.
CPU to NB Frequemcy:
200/400/600/800/1000 MHz

Flash Protect
This function protects the BIOS from accidental corruption by unauthorized users or
computer viruses. When enabled, the BIOS data cannot be changed when attempt-
ing to update the BIOS with a Flash utility. To successfully update the BIOS, you will
need to disable this Flash Protection function. Setting options: [Enabled], [Disabled].
Primary Graphics Adapter
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
[PCI Express]
The system initializes the installed PCI Express card first.
If an PCI
Express card is not available, it will initialize the onboard VGA card.
[Onboard]
The system initializes the onboard VGA card first.
OnChip and PCIe VGA selection
This setting allows you to enable both OnChip and PCIe VGA, or enable PCIe VGA
only. Setting options: [Disbale Onchip VGA if have PCIe VGA], [Both exist and OnChip
VGA by frame buffer select].
OnChip VGA Frame Buffer Size
Frame Buffer is the video memory that stores data for video display (frame). This
field is used to determine the memory size for Frame Buffer. Larger frame buffer
size increases video performance. Setting options: [Disabled], [16MB], [32MB], [64MB],
[128MB].
RGB/TV Display
This item allows you to select an display device to display. Setting options: [Auto],
[RGB], [TV].
