    APIs that can be used for controlling the video display from an application. Standard Mode 3 vs Graphics Mode The 6400 Computer is CGA compatible in standard modes. In these modes, you can write directly to the video memory. Since the BIOS puts the system into graphics mode 43h, whenever the character size is changed from 8x8, the video memory could produce undesired results if your application writes directly to the video memory.

    However, one change has been made to COMMAND.COM to make it more useful on the 6400 Computer, as described later in this section. If you prefer to use the unmodified version of COMMAND.COM, you can get it from the full DOS option, available on diskette.

    Reference, System Information Boot Process The following paragraphs describe the various methods used to boot the 6400 Computer. Also described are the options that are possible during the boot process, which you exercise by holding a key down during the boot phase or by reconfiguring a CMOS setting.
  • Page 193 In standard PCs, the CMOS RAM is usually the only memory that is maintained by a backup battery. In contrast, all memory in the 6400 Computer is maintained at all times, with a fully charged backup battery. This memory can be maintained for approximately 100 hours in the event of a main battery failure.

    Reference, System Information signature has been validated, the corresponding BIOS extension is made active (or posted). Currently the 6400 Computer includes the following BIOS extensions: the Datalight, Inc., Cardtrick Flash File System and ROM DOS 5 (ROMDOSLO.BIN). The Flash File System is already located and executed prior to this stage of the boot process since it resides in the address range of D000:0 through D7FF:F.

    0 KB of extended memory is reported. Boot Drive Selection The 6400 Computer always boots DOS 5 from ROM, (that is, it never loads IO.SYS and MSDOS.SYS from a boot drive). CONFIG.SYS and AUTOEXEC.BAT files are read from the default drive whenever the files are present.
