Hi, some voices whisper that EFI programs are so much easier and simpler than Open Firmware. I am not making any statement but let you, much valued readers, decide here: http://www.osxbook.com/book/bonus/chapter4/efiprogramming/ vs: http://www.kernelthread.com/hanoi/src/hanoimania/hanoi.macprom Regards, Stefan

Sparc progress, sort of

by Blue Swirl

I noticed that when using the preloaded kernel, the kernel has 4 bytes memory corruption at address 0xf001000c (physical 0x1000c). The corrupting value is 0x7ffffffff, MAXINT. If I restore the original value manually from gdb session, Linux boots much better. I haven't yet found where the corruption happens. I made a dirty (don't commit this) version which takes the hardcoded prom tree and tree browsing functions from Proll. If OLD_OBP is enabled, the version can boot Linux as well as Proll/Qemu can at the moment, meaning that we can reach the userland installer without any faults. There could be bugs in the Forth-based tree, or maybe calling Forth is not working so well after Linux has started doing more things. _________________________________________________________________ Express yourself instantly with MSN Messenger!

Re: [OpenBIOS] old shoes vs new shoes.

by Asif Haswarey

My 2 pennies, I know EFI device driver developers here at work and I know for sure that among other things EFI's debugging framework is not as powerful as OpenFirmware. Heck! you can literally _interactively_ develope an FCode driver in OpenFirmware. This you cannot do in EFI. Perhaps OpenBIOS will be to EFI/x86Bios, what Linux is to Windows today. We'll find out within the next ~5 years. _____________ Asif Haswarey C1069W QLogic Corporation 26650 Aliso Viejo Parkway Aliso Viejo, CA 92656 Phone: 949.389.7607 Fax: 949.389.6308 -----Original Message----- From: openbios-bounces(a)openbios.org [mailto:openbios-bounces@openbios.org] On Behalf Of Ronald G Minnich Sent: Tuesday, May 23, 2006 9:42 AM To: The OpenBIOS Mailinglist Subject: Re: [OpenBIOS] old shoes vs new shoes.

And, fortunately, the API is totally new and incompatible with EVERYTHING, and it's not a very good API, so we get the benefit of having to learn a whole new api, with a special toolchain, that is useless for everything else we do. I am sure I have not listed all the benefits of this new EFI operating system :-) ron -- OpenBIOS http://openbios.org/ Mailinglist: http://lists.openbios.org/mailman/listinfo Free your System - May the Forth be with you
