VR-N100U USERS MANUAL
Page 78 of 98 All Items Are Subject To Change Without Notice Feb. 2004 Rev 1.0
6.1.1. Processor
Due to the optimized and multi-threaded Operating System that is installed on the industrial server board, VR-N100U is able to
achieve fast performance utilizing Intel Socket 370 based processors on the embedded platform. The board is designed to
automatically detect and support a wide variety of these processors.
NOTE: The VR-N100U comes standard with the fastest Intel Server Processor and highest quality low-profile heat sink fan
integrated onto the system.
6.1.2. Memory
The VR-N100U comes standard with 512MB of total memory.
NOTE1: The VR-N100U comes standard with the maximum memory configuration (512MB of PC133).
NOTE2: 512MB SDRAM DIMMs are NOT supported, therefore you must use two (2) 256MB SDRAM DIMMs to achieve the
maximum memory capacity.
6.1.3. Onboard ATAPI
The board comes fully equipped with the multiple onboard ATAPI/IDE Channels. It is capable of supporting any ATAPI-based
devices. The ATAPI device can be manually set to support any of three settings (Master, Slave or Cable Select).
VR-N100U offers onboard RAID storage, therefore four identical hard drives should be installed in the VR-N100U Rackmount
System. All hard drives must be set to MASTER and utilize IDE2, IDE3, IDE4 and IDE5 Channels only.
Channel Maximum Speed Channel Maximum Speed
IDE 0* ATA/100* IDE 4** ATA/133
IDE 1 ATA/100 IDE 5** ATA/133
IDE 2** ATA/133
IDE 3** ATA/133
NOTE1: ‘*’ IDE0 is occupied by the onboard non-volatile flash disk, thus we recommend not to attach any devices to this
channel.
NOTE2: ‘**’ IDE1 is currently not used by VR-N100U and its IDE cable will not be attached to a device at this time.
NOTE3: ‘**’ IDE2 to IDE5 are used for the four (4) VR-N100U RAID hard drives.
NOTE4: We recommend that you utilize ANSI standard 40-pin 80-conducted IDE Cables for ATAPI Channels (IDE1 and
above). The IDC connector MUST HAVE all 40 pins open on the (Blue) host connector.
6.1.4. Onboard SCSI
The board can come standard with an onboard SCSI Channel. The Adaptec Ultra160-LVD/SE SCSI is capable of supporting
any SCSI-1, SCSI-2, SCSI-3, Narrow, Ultra, Wide, Ultra Wide, LVD160, and LVD320-based devices. The SCSI device support
is dependent on the VR-N100U installed device drivers.
