- BIOS32: As a demonstration, load a BIOS expansion ROM (the one I've tested is the "OS in PCI expansion ROM" from: https://sites.google.com/site/pinczakko/building-a-kernel-in-pci-expansion-rom ; we don't support PCI thingies at all, but the bootstrap code works correctly). - Initialize the BIOS32 stack for the callbacks. - In the common BIOS functions, if we try to load the Windows NTVDM (SoftPC) BIOS (file: bios4.rom), we immediately hit a BOP 0x00 followed by INT 0x19 (bootstrap to run an OS). The BOP 0x00 is the function used by the BIOS to ask NTVDM to initialize the hardware, the IVT with data and so on. Also we finish to load the low part of the NTVDM BIOS in it (file: bios1.rom). It's work-in-progress, nothing is done, there are lots of debugging code... Have fun! (to load a custom bios you need to put its filename as the first parameter of the BiosInitialize call, in the main() function in ntvdm.c). svn path=/branches/ntvdm/; revision=62333 |
