3.4 DEVICE DRIVER CONFIGURATION FILES CONFIGURING THE FIRST STAGE A separate configuration file is included for each device driver provided with the Bootstrap Loader. These files are named B208.A86, BMSC.A86, B218A.A86, B224A.A86, B251.A86, B254.A86, B264.A86, B552A.A86, and BSCSI.A86. Each consists of an include statement and a macro call. The source file always has the form where: $include( :fl: bxxx.inc) %bxxx( parameters) xxx Either 208, MSC, 218A, 224A, 251, 254, 264, 552A or SCSI, depending on the device driver. The number and type of parameters that are included with each macro depend on the device driver. The parameters for each macro are discussed in the following sections. Additionally, when a SASI controller board is used with the SCSI device driver, it requires another macro. Refer to the "%BSCSI Macro" and "%SASI UNIT INFO Macro" sections for details and for invocation examples. The default parameter vahles for the macros in these sections are compatible with the default parameter values of the iRMX Start-up Systems. You should examine one of these files for each type of device you want the first stage of the Bootstrap Loader to support. Usually, you can use the Intel-supplied files. The following sections describe the individual macros so you can make changes to them, if necessary. 3.4.1 %8208 Macro The %B208 macro is used to configure the Bootstrap Loader driver for the iSBC 208 controller board. The %B208 macro has the form where: %B208(io _base) io base I/O port address selected Gumpered) on the iSBC 208 controller board. The default invocation of this macro in the B208.A86 file is %B208(180H) Bootstrap Loader 3-33
CONFIGURING THE FIRST STAGE 3.4.2 %BMSC and %B220 Macros 3-34 The %BMSC and %B220 macros are used to configure the Bootstrap Loader driver for the iSBC 214, iSBC 215G, iSBC 220 and iSBC 221 controller boards. The BMSC.A86 file contains two macros, %BMSC and %B220. However, you can use only one. If you have one of the drivers listed in the Note at the bottom of Table 3-1, you should use the %BMSC macro. If you have the iSBC 220, you should use the %B220 macro. Both macros have the form where: %Bxxx (wakeup, cylinders, fixed_heads, removable_heads, sectors, dev _gran, alternates) xxx Either MSC or 220. wakeup Base address of the controller's wakeup port. The remaining parameters are used to specify the characteristics of the disk drives. If the %DEVICE macro you used for MSC or iSBC 220 devices in the BS l.A86 or BSIMB2.A86 file has deviceinitmsc (rather than deviceinitmscgen) as its third parameter, then all MSC or iSBC 220 drives used by the Bootstrap Loader must have the characteristics listed in the following parameters. That is, they must have the same number of cylinders per platter, fixed heads, removable heads, sectors per track, bytes per sector, and alternate cylinders. However, if the %DEVICE macro specifies deviceinitmscgen,these restrictions do not apply and the following parameters are not used by the Bootstrap Loader. cylinders fixed heads removable heads sectors alternates Number of cylinders on the disk drive or drives. Number of heads on fixed platters. Number of heads on removable platters. Number of sectors per track. Number of bytes per sector. Number of cylinders set aside as backups for cylinders having imperfections. Bootstrap Loader
