Well, it's written in a very interesting way. They do recommend to have=20 _DSM method in order to support 64bit. It is quite possible that the source of the problem is somewhere else. Actually it is also quite interesting to know what is the resource=20 window for 440FX? Perhaps Windows OS does not believe that 440FX=20 supports 64bit PCI resources. But I see no way to check this. >> Unfortunately I'm not familiar with ACPI code of seabios, so can't >> implement the _DSM method. May be you have other ideas what needs to >> be done to fix it? Any help is appreciated. >> >> Thanks, >> Alexey > Could you share some more detail about your setup? > Ok Here are logs the faulty device is: 00:05.0. In the first case the BAR1 size is 512MB and it fails in Windows (Linux=20 is fine, the kernel enumerates the bus and assigns the resource above 4GB= ), In the second case the BAR1 size is 256M and works fine. The first one causing issues. As PCI memory region for 00.0.5 is not=20 assigned after windows boot. (Note. I also tried to supply a particular=20 physical addresses over 4GB in pciinit.c code but this leads to=20 completely the same behaviour. Windows just don't pick-up the resource.) --------------------- Seabios log PCI BAR 512MB:=20 ------------------------------------ Changing serial settings was 0/0 now 3/0 Start bios (version pre-0.6.3-20111201_162012-core-3000-3.et.endace.com) enabling shadow ram qemu_cfg_present=3D1 Find memory size Ram Size=3D0xe0000000 (0x0000000320000000 high) malloc setup Relocating init from 0x000e01c0 to 0xdffe0980 (size 62800) malloc fixup reloc init ivt init bda init pic init timer CPU Mhz=3D2801 math cp init init mtrr pci setup =3D=3D=3D PCI bus & bridge init =3D=3D=3D PCI: pci_bios_init_bus_rec bus =3D 0x0 =3D=3D=3D PCI device probing =3D=3D=3D PCI probe PCI device 00:00.0 (vd=3D8086:1237 c=3D0600) PCI device 00:01.0 (vd=3D8086:7000 c=3D0601) PCI device 00:01.1 (vd=3D8086:7010 c=3D0101) PCI device 00:01.2 (vd=3D8086:7020 c=3D0c03) PCI device 00:01.3 (vd=3D8086:7113 c=3D0680) PCI device 00:02.0 (vd=3D1013:00b8 c=3D0300) PCI device 00:03.0 (vd=3D10ec:8139 c=3D0200) PCI device 00:05.0 (vd=3Deace:eace c=3D0280) PCI device 00:06.0 (vd=3D1af4:1002 c=3D0500) Found 9 PCI devices (max PCI bus is 00) =3D=3D=3D PCI new allocation pass #1 =3D=3D=3D PCI: check devices bus 0 =3D=3D=3D PCI new allocation pass #2 =3D=3D=3D PCI: init bases bus 0 (primary) type io max 100 sum 150 base c000 size 100: 1 bar(s), c000 -> c0ff size 20: 2 bar(s), c100 -> c13f size 10: 1 bar(s), c140 -> c14f type mem max 10000 sum 32000 base febc0000 size 10000: 3 bar(s), febc0000 -> febeffff size 1000: 2 bar(s), febf0000 -> febf1fff type prefmem max 2000000 sum 2000000 base fc000000 size 2000000: 1 bar(s), fc000000 -> fdffffff PCI: map device bus 0, bfd 0x0 PCI: map device bus 0, bfd 0x8 PCI: map device bus 0, bfd 0x9 bar 4, addr c140, size 10 [io] PCI: map device bus 0, bfd 0xa bar 4, addr c100, size 20 [io] PCI: map device bus 0, bfd 0xb PCI: map device bus 0, bfd 0x10 bar 0, addr fc000000, size 2000000 [mem] bar 1, addr febf0000, size 1000 [mem] bar 6, addr febc0000, size 10000 [mem] PCI: map device bus 0, bfd 0x18 bar 0, addr c000, size 100 [io] bar 1, addr febf1000, size 100 [mem] bar 6, addr febd0000, size 10000 [mem] PCI: map device bus 0, bfd 0x28 bar 0, addr febe0000, size 10000 [mem] bar 1, addr 0, size 20000000 [mem] PCI: map device bus 0, bfd 0x30 bar 0, addr c120, size 20 [io] PCI: bus=3D0 devfn=3D0x00: vendor_id=3D0x8086 device_id=3D0x1237 PCI: bus=3D0 devfn=3D0x08: vendor_id=3D0x8086 device_id=3D0x7000 PCI: bus=3D0 devfn=3D0x09: vendor_id=3D0x8086 device_id=3D0x7010 PCI: bus=3D0 devfn=3D0x0a: vendor_id=3D0x8086 device_id=3D0x7020 PCI: bus=3D0 devfn=3D0x0b: vendor_id=3D0x8086 device_id=3D0x7113 PCI: bus=3D0 devfn=3D0x10: vendor_id=3D0x1013 device_id=3D0x00b8 PCI: bus=3D0 devfn=3D0x18: vendor_id=3D0x10ec device_id=3D0x8139 PCI: bus=3D0 devfn=3D0x28: vendor_id=3D0xeace device_id=3D0xeace PCI: bus=3D0 devfn=3D0x30: vendor_id=3D0x1af4 device_id=3D0x1002 init smm boot order: 1: /pci@i0cf8/ide@1,1/drive@0/disk@0 2: /pci@i0cf8/ide@1,1/drive@1/disk@0 Found 2 cpu(s) max supported 2 cpu(s) init bios32 init PMM init PNPBIOS table init keyboard init mouse init PIR table init MPTable MP table addr=3D0x000fda00 MPC table addr=3D0x000fda10 size=3D260 init SMBIOS tables SMBIOS ptr=3D0x000fd9e0 table=3D0x000fd880 size=3D346 init ACPI tables ACPI tables: RSDP=3D0x000fd850 RSDT=3D0xdfffd740 Scan for VGA option rom Attempting to init PCI bdf 00:02.0 (vd 1013:00b8) Copying option rom (size 35840) from 0xfebc0000 to c0000 Running option rom at c000:0003 Turning on vga text mode console SeaBIOS (version pre-0.6.3-20111201_162012-core-3000-3.et.endace.com) init usb UHCI init on dev 00:01.2 (io=3Dc100) /dffdf000\ Start thread /dffde000\ Start thread /dffdd000\ Start thread \dffdd000/ End thread init ps2port /dffdd000\ Start thread init lpt Found 0 lpt ports init serial Found 1 serial ports init floppy drives init hard drives ddr 0 ATA controller 1 at 1f0/3f4/0 (irq 14 dev 9) /dffdb000\ Start thread ATA controller 2 at 170/374/0 (irq 15 dev 9) /dffda000\ Start thread init ahci init virtio-blk |dffdb000| ata0-0: QEMU HARDDISK ATA-7 Hard-Disk (51200 MiBytes) |dffdb000| Searching bootorder for: /pci@i0cf8/*@1,1/drive@0/disk@0 |dffdb000| Registering bootable: ata0-0: QEMU HARDDISK ATA-7 Hard-Disk=20 (51200 MiBytes) (type:2 prio:1 data:fd800) \dffdb000/ End thread |dffda000| DVD/CD [ata1-0: QEMU DVD-ROM ATAPI-4 DVD/CD] |dffda000| Searching bootorder for: /pci@i0cf8/*@1,1/drive@1/disk@0 |dffda000| Registering bootable: DVD/CD [ata1-0: QEMU DVD-ROM ATAPI-4=20 DVD/CD] (type:3 prio:2 data:fd7d0) \dffda000/ End thread |dffde000| set_address 0xdffe0150 |dffde000| config_usb: 0xdffdccec |dffde000| device rev=3D0100 cls=3D00 sub=3D00 proto=3D00 size=3D08 |dffde000| usb_hid_init 0xdffdccec \dffde000/ End thread \dffdf000/ End thread |dffdd000| PS2 keyboard initialized \dffdd000/ End thread All threads complete.
