Hibernation?
by lbios_kk＠redfenix.com 02 Jun '04

02 Jun '04

I'm sure if someone has thought of doing this before, but I haven't found mention of it anywhere. Has any work been done toward the goal of "Hibernation"? I'm writing of the type that would use a separate partition equal to ram + swap space to store the current memory state. If no one has done any work to this effect, how difficult would it be? I may be willing to help the effort. I've never programmed for a BIOS, but I've done mmap() stuff before. --Kevin

Chipsets: status page?
by Joshua Wise 01 Jun '04

01 Jun '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I read the FAQ looking for information on chipsets supported in LinuxBIOS, and it pointed me towards the status page, however I can only find information about mainboards on that page. Am I looking in the wrong place? For reference, I'm wondering if the AMD-760 and the VIA VT82C686 are supported.

Native LinuxBios Support
by Mathieu Deschamps 01 Jun '04

01 Jun '04

Hello, I've rere-reread LinuxBios port to AMD64 guide during some documentation making. I am wondering about Linuxbios Native Support and VGA init... Linuxbios is supposed to support "Trident Cyberblade 3d" natively and I have a Cyberblade/i1 rev 6a in my chipset... Please don't tell me that I've spend time making it work, though it isn't really, while there is a native support ?!? this must be a joke ! If not and that is tue and after i eat my jeans on the go, is that meaning that i've just to set CONFIG_VGABIOS and that would be all ? mathieu

Has anyone heard about EPIA MII FastBoot ROM Utility?
by Ignacio Verona 31 May '04

31 May '04

Hi! Here http://www.viaarena.com/?PageID=343 under Booting Utility I've found what via calls FastBoot ROM. It says we can boot from PCMCIA-CompactFlash and MDOC on epia MII, and source code is provided. I'll be givin a try this week, because it will be nice to my proyect if I can boot from CF, so I can forgot about using harddisk. What do you think about? Anyone has used this?

Welcome! Did you have anything specific in mind? A specific mainboard that you want to work on, perhaps?

testbios: other chips?
by Joshua Wise 28 May '04

28 May '04

I've seen various success stories of testbios being used to execute VGA BIOSes and get VGA cards running. This led me to ask the question of whether it would be feasible to get BIOSes from other option cards, such as my "00:13.0 Unknown mass storage controller: Triones Technologies, Inc. HPT366/368/370/370A/372 (rev 04)" to execute and initialize. Thanks, joshua -- Joshua Wise | www.joshuawise.com GPG Key | 0xEA80E0B3

Know someone available for a freebios port to an SMP Opteron motherboard? (fwd)
by Hendricks David W. 28 May '04

Any takers? ---------- Forwarded message ---------- Date: Fri, 28 May 2004 13:52:18 -0700 From: William J. Earl <earl(a)agami.com> To: ollie(a)users.sourceforge.net, ebiederm(a)users.sourceforge.net, dhendricks(a)users.sourceforge.net Subject: Know someone available for a freebios port to an SMP Opteron motherboard? I am working with freebios for an SMP Opteron motherboard, but I am very new to the source base. Would you know of anyone who might be available for a short contract to configure and bring up freebios on a new Opteron motherboard? I have the relevant documentation and the cooperation of the vendor, and working boards. I am writing to you as you have recently been checking in improvements to freebios for Opteron.

You got time for USB boot debug? Do you have any idea about: USB device control ed works well, but the bulk ed doesn't work, USB report device not responding? Does the code in baremetal work? In the code, signature of cbw and csw define missed 0x.

Greetings, I'm finally getting dug out after being snowed under :-) The spec is probably part of: http://www.usb.org/developers/devclass_docs/usbcdc11.pdf The communications class. I'm guessing it would be a subset of POTS modem with a transparent data protocol. That would imply line contol on the control ep, and either bulk transfer or isochronous pipe pairs for the serial data. It's a lot more involved than a simple UART, that's for sure. On a side note, I THOUGHT I would have time by now to bang on the USB boot. Hopefully, I'll be able to do more with it now (so I say :-) As soon as I get up to speed on freebios2, I'll have a good test platform. For the serial, UHCI and OHCI will be good. EHCI can likely be ignored for the BIOS since fast devices are required to fall back and EHCI always has one of UHCI or OHCI to handle low speed USB.

After I get USB boot done, I will try that and modify the auto.c.....

The code is feature complete so it will correctly not inline functions (producing smaller code) if it does not run out of registers. My simple test cases have worked well. My complicated test case that uses an old version of production code ran out of registers after consuming just the 8 general purpose registers. So mostly it is a matter of playing with the code, and figuring out why weird things are happening. Eric
