Added comments. Removed boot disk value update, since BIOS hands us the boot disk in dl, when the bootstrap is called. by convention. SPR#745201o,01oct99,hdn added support for binary file.01n,08apr99,jkf corrected warning, SPR#26453.01m,27aug98,dat added config.h, #ifdef INCLUDE_TFFS.01l,04mar98,hdn fixed a problem in mkbootTffs().01k,03mar98,kbw made changes to man page text for mkbootTffs01j,15dec97,hdn added support for TFFS.01i,15feb96,hdn renamed to mkboot.c01h,12jun95,hdn added support for ATA. added mkbootFd and mkbootAta.01g,24jan95,jdi doc cleanup.01f,25oct94,hdn added fdRawio() instead of using raw file system. swapped 1st and 2nd parameter of vxsys().01e,28may94,hdn updated the boot sector to DOS version.01d,27jan94,hdn changed the entry point 0x10000 to 0x8000.01c,16nov93,hdn changed name of the boot image "bootrom.dat" to "bootrom.sys".01b,07nov93,hdn adopted Dave Fraser's idea.01a,12oct93,hdn written*//*DESCRIPTIONThis library creates a boot diskette or disk. mkbootFd() creates a bootfloppy disk, mkbootAta() creates a boot IDE/ATA disk.NOMANUAL*/#include "vxWorks.h"#include "config.h"#include "a_out.h"#include "errnoLib.h"#include "ioLib.h"#include "stdio.h"#include "string.h"#include "usrLib.h"#include "dosFsLib.h"#include "drv/fdisk/nec765Fd.h"#include "drv/hdisk/ataDrv.h"#include "usrFdiskPartLib.h"#ifdef INCLUDE_TFFS#include "tffs/tffsDrv.h"#endif /*INCLUDE_TFFS */#define VXSYS_FD 0 /* floppy disk */#define VXSYS_ATA 1 /* ATA disk */#define VXSYS_TFFS 2 /* flash memory: DOC */#define VXSYS_DOSDEV "/vxsysdos/"/* * VXLONGNAMES will store the "." confusing the bootstrap, FAT/VFAT wont. * so we remove the "." for the bootStrap code on longnames detection. *//* MUST MATCH string in bootStrap array.. */#define VXSYS_FILE "/vxsysdos/BOOTROM.SYS"#define VXSYS_FILE_VXEXT "/vxsysdos/BOOTROM SYS"#define AOUT_MAGIC_MASK 0x0000ffff /* a.out magic number mask */#define AOUT_MAGIC 0x00000107 /* a.out magic number */ #define VXDOS "VXDOS"#define VXEXT "VXEXT"#define MAX_SECTOR_SIZE (8 * 512)/* 448 bytes for bootstrap, + 2 bytes (55aa) signature */#define BOOTSTRAP_AND_SIGNATURE 450 /* global */int vxsysDebug = 0;/* local */LOCAL BOOL vxsysBootsec = TRUE;LOCAL BOOL vxsysBootrom = TRUE;
