fixing coding style in bios source files (#6) 
Co-authored-by: Stanislav Shwartsman <sshwarts@users.sourceforge.net>
 2022-07-17 18:16:44 +03:00
Volker Ruppert 52b0000db7 Applied two patches from Debian. 
- Apply standard flags from environment everywhere (SF patch #546).
- Allow overriding ld and objcopy for building bios on non-x86 platforms.

Volker Ruppert 7ed5d6447a Fixed two SF bugs in the Bochs BIOS code. 
- MS-DOS 4.01 caused a stack overflow in the int15_function(). Now handle all
  functions that simply return success in the ASM code. Fixes SF bug #1439.
- Added two delay loops in keyboard_init(). Fixes SF bug #1438.

Volker Ruppert caf52aacac Added advanced PCI option 'noagp' for the i440BX chipset. 
Since AGP support is incomplete, it may be useful to disable this subsystem.
