Under Windows NT 4. 0 PC Card devices are not able to respond to power management events such as entering standby mode. As such, power management functionality can lead to unexpected results when PC Cards are in use under native Windows NT 4. 0. The way a particular PC Card behaves in response to power management events depends to a large extent on the direct enabler provided by the PC Card vendor. Contact your PC Card vendor directly for more information should you have a need to use a particular device without the benefit of CardWare® 5. 0. Another key feature CardWare® 5. 0 delivers is full support for the Advanced Power Management (APM) specification, version 1. 2. PC Cards used in conjunction with CardWare® 5. 0 operate more reliably when responding to power management events. The only notable exceptions to the power management support with PC Cards are local area networking (LAN) and SCSI interfaces. These types of devices typically do not support standby or hibernation modes with or without CardWare® 5. 0. This limitation is not the result of any shortcoming in CardWare® 5. 0, but rather lack of a widely accepted standard for developing power management-aware software drivers. The PCMCIA is an industry association responsible for developing PC Card standards. The Association recently ratified an addendum to the PC Card standard that defined a workable solution for to more reliable PC Card operation in response to power management events. This addendum, known as Proposition 187 ­ The NT Bindings Proposal is new and many PC Card vendors have yet to release updated software drivers that incorporate this latest addition to the PCMCIA specification. Customers who require the highest levels of reliability and performance on Compaq portable platforms should insist on PC Card vendors whose products have been designed to meet the PCMCIA specification. For more information on selecting PC Card solutions recommended by Compaq, refer to the section titled Compaq PC Card Solutions Program. NOTE: Standby and hibernation are not fully supported when connected to a local area network or using a PC Card SCSI interface. Compaq recommends removing these types of devices from the PC card slots before entering either of these states. WHITE PAPER (cont. ) . . 5 Extended Feature Set Beyond CardBus support and enhanced power management, CardWare® 5. 0 adds a number of features not included in basic PC Card support provided by Windows NT 4. 0. This extended feature set greatly improves the overall usability of PC Card devices on Compaq portable products. Table 3 summarizes all major PC Card features supported on Compaq portable platforms using Windows NT 4. 0. . 6 Windows NT 4. 0 Native PC Card Support û CardWare® 5. 0 for Windows NT 4. 0 (v2. 0x) CardWare® 5. 0 for Windows NT 4. 0 (v2. 1x) Supported Features Hibernation with PC Cards9 Table 3 - CardWare® 5. 0 Feature Comparison by Version SUPPORTED P C C A R D TYPES Table 4 summarizes the various types of PC Card devices supported by CardWare® 5. 0 as compared with those supported by native Windows NT 4. 0.
