Re: Solved..

Once again, I seemed to have solved the problem myself. I wrote a little loader, which executes the code in the boot-sector of a Floppy, so that I'm able to load MS-DOS, even when only the boot block BIOS works. I checked how it works in Qemu with an MS-DOS 6.22 floppy image: qemu-system-i386 -bios...

Re: How insert 3 ISA option ROM to Award bios?

Yes, I noticed that PLOP may not work with certain VGA cards or when you enable the USB Keyboard Support in CMOS Setup. Please read this my post on PLOP forum: Note 1: In some Award BIOS'es e.g. Soltek SL-75DRV4 can not be enabled option USB Keyboard Support. If this is enabled then PLOP not start a...

Re: How insert 3 ISA option ROM to Award bios?

Do you still have enough free space in your bios? Did you check? Yes, of course bios have free space. CBROM add module OK but third ROM is not mapped to RAM. If add ISA e.g. like this: cbrom bios.bin /isa third.bin d900:0 after PC boot in DEBUG.EXE (MS-DOS) check memory and no code 55AA.... only FF...

Re: Is it possible to change the size of the BIOS?

I think that you do not need to unpack any modules. I tried increase size 256K to 512K Award bios 6.00PG in this way: bios.bin 256K = 262144 bytes (40000h) BootBlock -> 8192 bytes (2000h) bios.bin-bootblock: 40000-2000=3E000 (253952 bytes) in HEX editor copy BootBlock 8192 bytes to new file second.b...

Award 6.00PG bioses work on Bochs 2.6.2 for Windows

Hi. I spent a lot of time to test the Award BIOSes that run in the emulator Bochs 2.6.2 for Windows. I found about 10 working Award 6.00PG BIOSes, most of this list: Intel Solano i815(E) with Award BIOS v6.00 chipset based motherboards using Award BIOS IDs . To run bios you need simply replace main ...

Re: PCI Option ROM in VMWARE

I tried also test maman PCI Protected mode OS in VMware. This only work on real machines e.g. Award BIOS 6.00PG, virtual machines MS VPC 2007 and also Qemu with seabios :-). I make ISA option ROM code from maman PCI code. Read this topic on flatassembler forum. http://board.flatassembler.net/files/q...

Re: My guide to award BIOS reverse engineering

To use Award bios in Bochs emulator need simply change default bios file in Memory settings or change file name e.g. 616AFA03.BIN to BIOS-bochs-latest. http://savepic.net/4355883m.png P.S. I found other working bios'es Award. Some bioses simply not work, other boot only Award BootBlock. I start test...

Hi maman. 1.) In your Guide to Award BIOS reverse engineering , you mention that you are not really sure what the ROSUPD.bin mofule is: "ROSUPD.bin, seems to be custom Logo display procedure" Could it be that the module + is a "container file" (like an uncompressed zip/rar/... archive)? + contains ...
