Re: What does bochs put at 0x30000

Hi, according to Bochs BIOS sources this is 64K-size BIOS_TMP_STORAGE which is used to copy the BIOS into the shadow RAM.

The copy itself done by function 

static void bios_shadow_init(PCIDevice *d)

which is used only from pci_bios_init.

 

I guess it is safe to overwrite because BIOS won’t use it after initialization.

Subject: [Bochs-developers] What does bochs put at 0x30000

 

Hi everyone,

 

I noticed that the bochs BIOS puts some data at 0x30000. It ends at 0x304F0. I was wondering what it is. Can my OS erase it? Or use it for something?

 

Thank you very much,

Isaac D. Cohen
