Toshinden (CGL) for 3DBPCI tries to access these memory addresses before crashing:
0xA0F00012
0xC0F00014.

The staring digits suggest to me that page A0F00 is remapped VGA RAM and C0F00 is the remaped video BIOS (Segments A000 and C000).

In Windows '98 these addresses aren't directly used resources for the 3DBPCI.

@robertmo3, after my changes I get this:

Aargh! It was caused by a custom build option ('renditionV1000pci'). It's not set up correctly.

Thanks!

@robertmo3, do you know where this has to be defined CONFIG_VGA_CIRRUS for the cirrus vga driver files to be compiled?

I've got my own pre-processor define CONFIG_VGA_RENDITION defined and I've set it up in:
config-poison.h
and
i386-softmmu-config-devices.mak

but it just ignores it.

how about just replace cirrus with your source under the cirrus name.
this way it may easier

That makes sense.

Which OS are you running under and what's your 2D card? Also can you check the MD5 checksum just to make sure my website isn't messing up. I did download it again from nirvtek.com/downloads to verify and it seems ok.

For instance under W98 with a 3DBPCI (which is also being studied at the moment) I get the attched file. What I'm really interested in is the first 4 int calls.

Does anyone know where I can get the VMWare disk mount utility? QEMU uses vmdk files.

The Broadcom/VMWare doesn't show up in a google search. A bunch of dodgy sites do though.

[EDIT] VMWare VMs can't access it, I think I need to reboot for that.

@robertmo, do you know how to build the seabios PC BIOS?

Nm, there's a makefile in there.

you can open hdd images in daemon tools lite
you can use the 2gb image from my qemu build

Supported HDD Image Formats:

RAW: A simple, byte-by-byte storage format that is easily exported to other emulators.
QCOW2: QEMU's primary image format offering features like snapshots, compression, encryption, and smaller images on filesystems that don't support sparse files.
VHD/VHDX: Hyper-V formats for interoperability with Microsoft's hypervisor.
VDI: VirtualBox format for compatibility with VirtualBox.
VMDK: VMware image format for interoperability.
Bochs: A format for growing type images.
Cloop: Linux compressed loop images.
dmg: Apple disk images.
Parallels: Parallels disk image format.

DAEMON Tools Lite 10 allows you to mount all known types of disc image files

just in case
all the needed bioses are here: qemu-10.0.0-rc4\pc-bios\
SeaBIOS (bios.bin)

I need to recompile the BIOS with some of my changes. It does't compile and its not because of my changes.

I need to copy some new stuff over to your 2 gb image.

just mount that hdd image in daemon tools lite

I'll try that.

Does anyone know what this error means:

1unable to begin graphics memory system: MX1 error 19

in the context of Nascar 1 with the Matrox Millennium 2 MB (IS-MGA-2064W, 2 MB).
