Appendix B. Advanced Information for PC Cards This appendix describes the Auto Configurator program, which automatically enables the PC Card without the device driver supplied with your PC Card being installed. It also explains some considerations you should be aware of when using your PC Card. Auto Configurator for the PC Card Director Program To install the PCMCIA device driver: Page 183. The Auto Configurator makes it possible for you to avoid installing the device drivers for some PC Cards.
Advanced Information for PC Cards Example When a Modem Card Is Used When a modem card is installed in the PC Card slot, the Auto Configurator assigns interrupt request levels and I/O window from the information in the following data file and tuple data of the modem card: [MODEM] CardID=MODEM,MD24X Port1=3F8,IRQ=4 Port1=2F8,IRQ=3 Port1=3E8,IRQ=3 Port1=2E8,IRQ=3 Starting from the first “Port1” line, the Auto Configurator tries to assign the resources from I/O window X'3F8' and interrupt request level 4 for t
Advanced Information for PC Cards Example of the Memory Area for the Card Services and 3270 Notes: 1. The Auto Configurator for OS/2 supports modem and data/fax modem PC Cards. 2. The Auto Configurator for DOS and Windows supports modem, data/fax modem, and 3270 emulation PC Cards. The following is an example of the memory area specified by the Card Services memory area and 3270 data file: A Resource Map Utility statement: DEVICE=C:\EZPLAY\DICRMU 1.
Advanced Information for PC Cards Operational Considerations for PCMCIA Consider the following according to your operating system: OS/2 Software Considerations for OS/2 The following is a sample of the CONFIG.SYS file for OS/2: : BASEDEV=PCMCIA.SYS /P ← Rule 1 BASEDEV=ICRMU 1.SYS ← Rule 1 BASEDEV=IBM2SS 1.SYS /D ← Rule 1 DEVICE=C:\OS2\MDOS\VPCMCIA.SYS DEVICE=C:\THINKPAD\COM.SYS DEVICE=C:\THINKPAD\AUTODRV2.SYS C:\THINKPAD\AUTODRV2.
Advanced Information for PC Cards DOS Software Considerations for DOS Keep in mind the following considerations when using PC Cards: Using a Software EMS with the PC Card Warning: When you update the EMM386 parameter in the CONFIG.SYS file using RAMSETUP, set the same address range as the one specified by the “/MA=” parameter of DICRMU01.SYS as “Adapter”.
Advanced Information for PC Cards Note: The procedure assumes that you are using “EMS386.EXE” as an EMS device driver. The following example shows the procedure for memory allocation when an adapter that requires 32KB of memory is installed (the required-memory space of the adapter cards might vary from one card to another). 1. Open your CONFIG.SYS file using a text editor. 2. Find the DEVICE statement containing “EMM386.EXE.” 3. Change the statement to: DEVICE=C:\DOS\EMM386.
Advanced Information for PC Cards Note: For more information, see Chapter 5 of the Dock I User's Guide. This maximizes the memory address range that is allocated for the PC Cards and SCSI adapter in the Dock I. This assumes the Dock I SCSI adapter is at the default allocation (X'CA000'—X'CBFFF'). Using several PC Cards – Modify the configuration file as in the following example (IBM token ring card + IBM Ethernet card + IBM 3270 card + modem + EMM386): < CONFIG.SYS > DEVICE=C:\DOS\EMM386.
Advanced Information for PC Cards For the preceding example, the memory map will be as follows: C000:0 EMS memory C300:0 C400:0 IBM Card Service s Token-ring shared RAM C800:0 CC00:0 Ethernet shared RAM Token-ring memory mapped I/O CE00:0 3270 shared RAM D000:0 EMS memory E000:0 DOS Updating the CONFIG.SYS File The following is a sample of the CONFIG.SYS file for DOS: : DEVICE=C:\DOS\EMM386.EXE RAM 1 24 frame=D X=C8 -CFFF ← Rule 1 : DEVICE=C:\THINKPAD\IBMDSS 1.
Advanced Information for PC Cards Rule 1 For you to use the software EMS driver (EMM386.EXE) with the PCMCIA drivers, the “X=” parameter must be specified for EMM386.EXE. This parameter specifies the memory range that is used by the PCMCIA drivers. (For more information see “Using a Software EMS with the PC Card” on page 235.) Rule 2 The Socket Services driver (IBMDSS01.SYS), Card Services driver (IBMDOSCS.SYS), Resource Map Utility (DICRMU01.SYS), and Power Management Utility ($ICPMDOS.
Advanced Information for PC Cards DOS Note: These procedures do not apply to the device drivers supplied with your PC Card. Releasing the PCMCIA Memory Area If you are using DOS 7.0 or later but not are using the PC Card, you can use the PCMCIA memory area as your application program memory area. There are two ways to make this available for application programs: Use the PCMCIAOF command. Use the DOS Multiple Configuration Function.
Advanced Information for PC Cards Note: See the sections in the DOS User's Guide about using the DOS operating system and configuring your system using multiple configurations for more information about the DOS Multiple Configuration Function. Using the DOS Multiple Configuration Function: Use the DOS Multiple Configuration Function to change the CONFIG.SYS file, and add the choice of loading the PCMCIA device driver. The CONFIG.
Advanced Information for PC Cards WIN Software Considerations for Windows If you are using Windows, specify the memory area for Windows so it does not conflict with the memory area for the PCMCIA device drivers. After completing the installation for Windows, update your SYSTEM.INI file as follows: 1. Open your CONFIG.SYS file using a text editor. 2. Find: DEVICE= [drive:][path] DICRMU 1.SYS /MA=mmmm-mmmm 3. Note the address range of the PCMCIA device drivers (mmmm-mmmm); then close the CONFIG.
