UEFI BIOS crash setting or adding BootNNNN variable

[Peter Wieland]

Hello,

Using the 0.94 BIOS, I'm seeing the UEFI BIOS crash when setting BootNNNN values under EFI_GLOBAL_VARIABLE.  For example if I try to copy Boot0001 (the USB boot string) to Boot0002:

shell> setvar Boot0002 -bs -rt -nv =--PciRoot(0x0)/Pci(0x17,0x0)/Pci(0x0,0x0)/Pci(0x8,0x3)/USB(0x0,x0)/HD(1,MBR,0x00000000,0x800,0xE6C000)

I get the following exception:

!!!! IA32 Exception Type - 0000000D    CPU Apic ID - 00000000 !!!!

EIP  - 010012D6, CS  - 00000010, EFLAGS - 00010286

FXSAVE_STATE - 3F0C7AC0

!!!! Find PE image (No PDB)  (ImageBase=008E9000, EntryPoint=008EA4EF) !!!!

I get the same exception if I try to set Boot0001 to the value it currently has

I do not see an exception if I try setting Boot0002 to Fv(07F426A2-5F6B-4ED5-9B35-6FF191BFB4DD)/Shell (the value of Boot0000)

Questions:

1. Is this crash known?

2. Is there a PDB file for the 0.94 BIOS?

Thanks,

Hi Pete,

Hi Peter,

 

Eng has not root caused this issue yet, but they are recommending using the “bcfg” command instead.  I’m looking at the corresponding parameters that you could use.  You can get all the bcfg flags with “bcfg -? –v”.
