58de498fca Bart's patch to fix compile with OW1.8

0b8ae53670 If FAT32 and a "backup boot sector" exists, also update the 
backup boot sector to the contents of the main boot sector.

953e7b2007 Use _dos_allocmem for OW, similar to the Turbo C technique. 
Split copy function into readfile and writefile functions.
Preserve time and date of kernel.sys and command.com.

94085ce923 Changed copy() to use a two pass algorithm: Now SYS first calls 
copy to read kernel and command.com into RAM, then updates the
boot sector, then calls copy again to write kernel and command
from RAM to disk. This reduces disk changes a lot when you do
SYS A: B: on a PC which only has 1 diskette drive ("DJ style").

7ae98cee2a Introduce VA_CDECL: only Turbo C 2.01 needs an explicit cdecl for printf, 
all other compilers can use it with pascal or "register" calling conventions.
Saves ~50 bytes for the init code.

e7f0852dbd correct sectors/track, head and hidden sector values if the boot sector 
disagrees with the default bpb (unless the default bpb says that the
number of hidden sectors is zero (usual for floppies)).

introduce generic_block_ioctl() function to handle all 0x440d ioctls
(inclusive locking)

9a3da2b737 Version 2.7 luchezar, tomehlert, ericauer 2003/8/5 
boot.asm modified to support non-512 byte sectors (e.g. 1.2 MB NEC diskettes)
  512 byte sector size check removed (although Eric's boot32ea.asm does require
    512-byte sectors, all LBA FAT32 volumes have 512-byte sectors anyway).
  boot.asm cleaned up and modified to support Metakern (by Tom, Eric and Lucho)
  bsDriveNumber updated by SYS even #ifndef STORE_BOOT_INFO (nothing in common)

Version 2.7beta, Luchezar Georgiev, 1 August 2003
  o  Now supports and includes the following new boot sectors:
       1) the combined CHS+LBA FAT12/FAT16 boot sector by Tom Ehlert (29 July)
       2) the CHS-only FAT32 boot sector -- as patched by Jon Gentle (08 July)
       3) the LBA-only FAT32 boot sector by Eric Auer and Jon Gentle (19 July)
  o  The old combined (CHS+LBA), no-CALCPARAMS, no-resizable, non-Ghostable,
     non-standard FAT32 boot sector and STORE_BOOT_INFO is no longer used.
  o  dump_sector() showed ASCII debug printout for the old sector only - fixed.
  o  Put a boot sector only if sector size = 512 (may it not be so in Japan?!).
     If non-512 byte sectors encountered, report to the fd-kernel mailing list.
  o  Now puts boot sector before copying kernel/shell so it works in WinNT now.
  o  check_space() now implemented at last (required significant modifications)
  o  New file system (FAT type) detection method according to a MS White Paper.
  o  Now BOOTONLY works even without a preceding boot sector image file name.
  o  Some minor code cleanups.

Bart: some cleanups to the above; replaced 386 code for CHS FAT32 by 8088 code.
use boot32lb.asm instead of boot32ea.asm
