| 2 | pj | 1 | The graphic driver works invoking the BIOS services through soft interrupts. |
| 2 | This can be done using x_callBIOS() or vm86_callBIOS(): the first solution |
||
| 3 | works in all the possible systems, but can be used only if the program is run |
||
| 4 | through X.exe, whereas the second one (vm86_callBIOS()) can be used also if |
||
| 5 | the system is booted using GRUB. The drawback of the vm86 based solution is |
||
| 6 | that it may crash some buggy systems (in particular, systems based on funny |
||
| 7 | video bioses that invoke soft INTs inside the BIOS). |
||
| 8 | |||
| 9 | This problem will be fixed in the future; for the moment, it is possible to |
||
| 10 | compile the library to use x_callBIOS (default) or vm86_callBIOS (add -DVM86 |
||
| 11 | to the c compiler options in the makefile - you can use C_OPT += -DVM86). |
