With that defconfig confirmed to be working, I tried adding a few other things,
including vga bios (to get external displays working):
```
CONFIG_VENDOR_LENOVO=y
CONFIG_CBFS_SIZE=0x200000
CONFIG_VGA_BIOS_DGPU_ID="10de,0ffc"
CONFIG_VGA_BIOS=y
CONFIG_IFD_BIN_PATH="descriptor.bin"
CONFIG_ME_BIN_PATH="me.bin"
CONFIG_GBE_BIN_PATH="gbe.bin"
CONFIG_VGA_BIOS_FILE="vgabios/8086,0166.rom"
CONFIG_HAVE_IFD_BIN=y
CONFIG_BOARD_LENOVO_W530=y
CONFIG_H8_FN_CTRL_SWAP=y
CONFIG_HAVE_ME_BIN=y
CONFIG_USE_ME_CLEANER=y
CONFIG_HAVE_GBE_BIN=y
CONFIG_MAINBOARD_USE_LIBGFXINIT=y
CONFIG_VGA_BIOS_DGPU=y
CONFIG_VGA_BIOS_DGPU_FILE="vgabios/10de,0ffc.rom"
CONFIG_PAYLOAD_EDK2=y
CONFIG_EDK2_BOOT_MANAGER_ESCAPE=y
# CONFIG_EDK2_FULL_SCREEN_SETUP is not set
```
However, CBFS at 2MB (0x200000) is too small to have VGA BIOS. Thus, I get this
error:
```

E: Failed while operating on 'COREBOOT' region!
E: The image will be left unmodified.
make: *** [Makefile.mk:1214: build/coreboot.pre] Error 1
```
Changing it to 3MB (0x300000) creates a successful build. I assume CBFS at 3MB
is acceptable/sane?
Btw, where do I find `CONFIG_EDK2_BOOT_MANAGER_ESCAPE=y` in menuconfig?

Bug #549: coreboot 24.05: SeaBIOS Windows 10/11 BSOD "ACPI BIOS ERROR"
(Thinkpad W530)
https://ticket.coreboot.org/issues/549#change-1881
* Author: Simon Dominic
* Status: New
* Priority: Normal
* Category: board support
* Target version: master
* Start date: 2024-07-31
* Affected versions: master
* Affected hardware: Lenovo ThinkPad W530
* Affected OS: Windows 10/11
----------------------------------------
When using the latest coreboot (i.e. using command `git clone
https://review.coreboot.org/coreboot`), which is currently 24.05, to build a
rom for Thinkpad W530, I get BSOD with "ACPI BIOS ERROR" when trying to boot
into Windows 10 or 11 from SeaBIOS. Even just booting from a Windows install
usb will show this error.
This is even with incorporating the vga bios files (so i can external displays
to work) - see my defconfig.
Did consider using EDK2 apparently Windows support is pretty solid, but could
never make a successful build - not that `make` command had errors, but once
flashing, would just having white underscore and have to recover with external
flashing. A separate issue to write about in and of itself, but I prefer
SeaBIOS so I'll be sticking with that.
I am quite new to coreboot - using for only about 2-3 months now. Let me know
if there is further information I should provide.
