Chapter 1: Introduction Onboard SCSI Onboard SCSI is provided with an Adaptec AIC-7899 SCSI controller chip, which supports dual channel, Ultra160 SCSI at a burst throughput rate of 160 MB/sec for each channel. The 370DER+ provides three SCSI ports: two internal 68-pin LVD Ultra160 connectors (on channels A and B) and one external 68-pin Ultra160 SCSI connector (shared with channel B). PCI Expansion Slots The 370DER+ has one 64-bit 66 MHz slot. Two riser cards are included with the system for use with 64-bit and 32-bit PCI cards. ATI Rage XL PCI Graphics Controller An onboard ATI graphics controller based on the Rage XL graphics chip is integrated into the 370DER+.
This onboard graphics controller includes 8 MB of onboard memory and fully supports sideband addressing. This onboard graphics package provides a bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus. Onboard Controllers/Ports An onboard IDE controller supports one floppy drive and up to four UDMA/33 hard drives or ATAPI devices. Onboard I/O ports include two COM ports, two USB ports, PS/2 mouse and keyboard ports, a video (moni- tor) port and a two 10/100 MB Ethernet (NIC) ports, which back each other up in case one port loses connection. The 370DER also has an onboard ATI graphics controller (see above).
Other Features Other onboard features that promote system health include eight voltage monitors, a chassis intrusion header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus protection and BIOS rescue. 1-5
