Visual Studio: Difference between revisions

where es is loaded with base address of your [[PE Binaries|PE]] file in memory, ecx will be loaded with the entry point relative to base address of PE file. Of course, if this is protected mode with a flat 4GB address space, use a register instead of using ES.

 

'''Note:''' The options and procedures described here are for VS.NET 2003. Similar procedures should work on earlier versions. Consult the MSDN or post to the forum if you have any questions.

 

* /ALIGN: 512

: Together, they set the [[Section Alignment]] and [[File Alignment]] to 512 bytes. My boot loader is not sophisticated enough to handle these being different. The downside is that restrictions (read-only, etc) on sections are meaningless, as they require page-granularity for hopefully obvious reasons.

Another option is to use a separate linker such as [[WLink]] with a linker script such as the one found on the [[Watcom]] page.

 

=== The Rebase Utility: ===

</pre>

and, in the example given above, it will base kernel.sys at 0xC0000000 and will base subsequent files at the next page-aligned address.

 

== Express 64 bit compilers ==

You can gain 64 bit compilers by installing the Windows SDK VC++ compilers (please note for VC10 SP1 you need to install the update)

 

In the 64 bit compilers you '''cannot:'''

 

This is why if you intend to do 64 bit development in MSVC++ you should have an external assembly layer (seperate versions for 32 bit and 64 bit), and if you want to avoid name decoration you need to declare them in a header file like this:

 

Give up OS dev!
