Looking for a printf like function
by G 3 25 Aug '09

25 Aug '09

I would like to print messages to the console. What function should I use to do this? Background information: Building OpenBIOS for Qemu. Emulated Computer: Macintosh.

feature request

25 Aug '09

I ask that a 'dir' word be added to OpenBIOS. This word is what allows the user to view the files on various disc using OpenBIOS command prompt.

[patch 0/6] sparc64 zero virtual memory page fixes
by Igor Kovalenko 22 Aug '09

22 Aug '09

Hi! This series do clean up several issues with openbios implementation trying to access zero virtual memory page. These changes are needed to prevent corrupting low memory space, albeit it is hard to verify without corresponding change to qemu which moves pci memory space above low 32bit space. Qemu part is not completed yet, so I use workaround for testing purposes. Change to package.fs dealing with NULL instance or package handles should be visible even witout changes to qemu (meaning more … [View More]
