/* This routine is intended to mimic the functions of the SYS command
|
|
* under MSDOS: to transfer a version of the operating system from a source
|
|
* disk to a destination such that the destination will be bootable.
|
|
*
|
|
* The requirements of the source disk is that it contain:
|
|
*
|
|
* 1) a command processor (COMMAND.COM)
|
|
* 2) a default set of device drivers (IBMBIO.COM)
|
|
* 3) an operating system (IBMDOS.COM)
|
|
* 4) a boot sector appropriate to the device drivers
|
|
*
|
|
* The requirements for the destination disk are either:
|
|
*
|
|
* 1) first two directory entries are empty
|
|
* 2) the first N clusters free where N = ceil (size IBMBIO/secPerClus)
|
|
* 3) there is enough room on the disk for IBMBIO/IBMDOS/COMMAND
|
|
*
|
|
* - or -
|
|
*
|
|
* 1) the first two directory entries are IBMBIO.COM and IBMDOS.COM
|
|
* or IO.SYS and MSDOS.SYS
|
|
* 2) the first N clusters are alloced to these files where N is defined
|
|
* above
|
|
* 3) there is enough room on the disk for IBMBIO/IBMDOS/COMMAND after
|
|
* deleting the IBMBIO/IBMDOS/COMMAND on the disk.
|
|
*
|
|
* Inputs:
|
|
* iDestDrive 0-based drive number of formatted drive
|
|
* for destination.
|
|
* bEmptyFloppy : TRUE if the floppy is empty; Useful when
|
|
* the floppy is just formatted; No need to check if
|
|
* it is Sysable;
|
|
* Returns: 0 Successful transferral of boot sector and files
|
|
* <> 0 error code.
