Understanding Device Drivers• A device driver is a software interface between an
operating system and a hardware device• Generally want to use the specific recommended
driver for a device• Affects stability and performance
• Driver updates are frequent and usually available from manufacturer
• Driver signing is used to verify that a driver has been tested
![Page 8: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/8.jpg)

Device Manager
• Primary tool for managing device drivers• Allows administrator to view and modify
hardware device properties• Should be used soon after Windows Server 2003
installation to verify device detection and functioning
• Accessible from Control Panel or Computer Management tool
![Page 9: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/9.jpg)

• Memory address ranges
• Interrupt request (IRQ) lines
• Resource settings configured from Resources tab of properties of hardware device in Device Manager
![Page 18: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/18.jpg)
18
Hardware Resource Settings (continued)

20
Direct Memory Access Channels
• Allow hardware devices to access system memory (RAM) directly
• Information transfer bypasses CPU• Common devices
• Hard and floppy disk controllers
• Sound cards
• CD-ROM drives
• DMA channel used by a device can be determined from Device Manager
![Page 21: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/21.jpg)
21
Input/Output Ranges
• Small dedicated memory areas• Allocated specifically for data transfer between
computer and hardware device• Type of device dictates size of memory area• I/O ports can be determined from Device Manager
![Page 22: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/22.jpg)
22
Interrupt Request Lines
• Used to gain attention of the system processor to handle some event
• Traditionally, each device had dedicated line• Trend is toward sharing lines, Windows Server
2003 supports sharing among some Plug and Play devices
• IRQ lines can be viewed and managed from Device Manager
![Page 23: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/23.jpg)
23
Memory Addresses
• Used for communication between a hardware device and the operating system
• Devices configured with dedicated, unique memory address ranges
• Windows Server 2003 will automatically allocate memory addresses for Plug and Play devices
• For legacy devices, address ranges usually specified in documentation
![Page 24: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/24.jpg)

25
Troubleshooting Resource Setting Conflicts
• Manual configuration of devices can lead to resource conflicts (overlaps and duplication of assignments)
• Two methods for checking for resource conflicts• Resources tab in properties of device using Device
Manager
• System Information tool
• To open, type msinfo32.exe in Run command
![Page 26: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/26.jpg)

Configuring Device Driver Signing
• Every built-in driver in Windows Server 2003 is digitally signed by Microsoft
• Signing ensures compatibility, quality, authenticity, verified to work with hardware
• Three possible driver signing verification options• Ignore: install any driver whether signed or not
• Warn: show warning if attempt is made to install unsigned driver
• Block: don’t allow installation of unsigned driver
![Page 29: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/29.jpg)

33
Roll Back Driver Feature
• Common for vendors to release new or updated drivers for hardware devices• Fix known issues, take advantage of updated features
• Driver updates sometimes result in system stability problems
• When update causes problems, roll back allows going back to a previous version
![Page 34: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/34.jpg)

36
Configuring Processor and Memory Settings
• Three basic areas to configure for optimal performance• Processor scheduling and memory usage
• Virtual memory
• Memory for network performance
![Page 37: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/37.jpg)
37
Processor Scheduling
• Allows you to configure how processor resources are allocated to programs
• Default is Background services (all running applications receive equal processor time)
• Can set to Programs (foreground application receives priority processor time)
![Page 38: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/38.jpg)
38
Processor Scheduling (continued)

![Page 39: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/39.jpg)
39
Virtual Memory
• Disk storage used to expand RAM capacity• Slower than RAM• Uses paging technique
• Blocks (pages) of information moved from RAM to virtual memory on disk
• On Pentium, pages are 4KB
• Paged out when not in use, reloaded into RAM when needed
![Page 40: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/40.jpg)
40
Virtual Memory (continued)
• Area allocated is called paging file• Default amount allocated when operating system
installed but should be tuned by administrator• Name of paging file is pagefile.sys• Location of paging file important• Two important parameters: initial and maximum
size
![Page 41: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/41.jpg)
41

42
Memory for Network Performance
• Memory used for both server functions and network connectivity functions
• Server functions use RAM and memory• Network connectivity uses only memory• If performance is poor, may need to tune network
memory parameters
![Page 43: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/43.jpg)

44
Hardware Profiles
• Set of instructions defining which devices to start and drivers to load when computer starts
• Profile 1 created when Windows Server 2003 installed, every device enabled
• Portable computers change set of hardware device available at different times
• Can create additional profiles to match situation
![Page 45: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/45.jpg)

![Page 46: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/46.jpg)
46
Configuring Power Options
• Default power scheme is Always On (monitor off after 20 minutes, hard disks never off)• Can select other predefined schemes or create custom
scheme
• Standby mode• Components shut down and memory is not written to
disk (if power goes out, memory information is lost)
• Power supply and CPU remain active
![Page 47: Chapter02 Managing Hardware Devices](https://reader036.vdocument.in/reader036/viewer/2022062513/556bf026d8b42a65458b4f11/html5/thumbnails/47.jpg)
47
