Zero Channel RAID 
The SE7501HG2 server board supports two Zero Channel RAID cards: the Intel
®
 SRCZCR RAID 
Adapter and the Adaptec* ASR-2010S RAID adapter.  This support is provided via hardware and 
BIOS support only on PCI-X Slot 2.  If either of these RAID cards is installed, then the SCSI 
interrupts are routed to the RAID adapter instead of to the PCI interrupt controller.  
Segment A:  32-bit/33 MHz PCI Subsystem 
The 32-bit / 33 MHz PCI segment includes the following embedded devices and connectors: 
•  Three 5 V keyed full-length, full height PCI expansion slots (PCI Slots 4, 5 and 6) 
•  Integrated ATI Rage XL video controller with 8 MB of on-board SDRAM 
 
32-bit/33 MHz PCI features include: 
•  Bus speed up to 33 MHz 
•  5 V signaling environment 
•  Burst transfers up to a peak of 132 MB/s 
•  8-, 16-, or 32-bit data transfers 
•  Plug-and-Play ready 
•  Parity enabled 
Video 
The system has an integrated ATI Rage XL 32-bit high-performance SVGA subsystem that 
supports the following: 
•  BIOS compatibility with all standard VGA modes 
•  8 MB of video memory 
•  Pixel resolutions up to 1600 x 1200 pixels per inch (ppi) in 8/16/24/32 bpp modes under 2D 
and up to 1024 x 768 ppi in 8/16/24/32 bpp modes under 3D 
•  Both CRT and LCD monitors up to 100 Hz vertical refresh rate
