[LinuxBIOS] Difference in IC schematics
by Anton 11 Apr '07

11 Apr '07

I would like to change flash-chip, which is soldered on my board onto another one. Keeping in mind the size of IC and it's format (DIP/PLCC32/SO8), what should I be aware of? Thanks.

[LinuxBIOS] Update on Idea
by Randall Philipson 11 Apr '07

11 Apr '07

As an experiential side note on the push tack knob idea, this process does not prevent one from putting the chip in backwards. By the time you realize what you have done, the knob is starting to melt, so do not attempt to remove the chip with the knob before turning the computer off and waiting for it to cool. Even then the integrity may be sufficiently damaged that you may need tools to extract it. Interestingly enough, push pins with the points still on worked surprisingly well for that although I recommend a chip puller if you have it Randy P.S. I'm sure this topic has already become tedious. I promise this is my last post on it (except responding to questions, if there are any).

[LinuxBIOS] Dumping BIOS on ASUS boards
by Anton 11 Apr '07

11 Apr '07

Could someone verify that dumping flash contents on following ASUS boards is possible? 1) ASUS A7V8X-X, VT8235, PMC_49FL002 2) ASUS A7V600, obviously the same, PMC_49FL002 flashrom should be 2581 or later revision. Thanks.

Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS. The developer "stepan" checked in revision 2602 to the LinuxBIOS source repository and caused the following changes: Change Log: Jeremy Jackson wrote: I'm guessing nobody has tried compiling it with 64bit userspace?

[LinuxBIOS] gigabyte motherboard
by john 11 Apr '07

11 Apr '07

Hello I'd like to buy a gigabyte M57SLI-S4 motherboard to experiment with Linux Bios. I notice that this board comes in two versions (rev 1.0 and rev 1.1). Gigabyte support web site indicates the rev 1.1 board supports a wider range of CPUs. Can someone tell me which one to use for Linux Bios or will either work? Thanks John =============

[LinuxBIOS] 32 Pin Dip Plug Cable
by roger 11 Apr '07

11 Apr '07

I probably should have posted this question prior to constructing this cable, but anybody heard of a "32 Pin Dip Plug Cable"? Scanning through the Digikey catalog, I'm seeing some with other pin numberings, but as to whether or not their sizing is correct for the 32 DIP pin connector of a bios chip is extremely questionable. http://www.eskimo.com/~roger/files/linuxbios/Photos/IMG_3357_32PinDipPlugCa… I am concerned about voltage/amps dropping, but so far reading from the chip works! (This means also I'm a great solder!) Writing is another story I'm about to experiment tonight with. (I used 26 stranded gauge wire for reference.) Soldering required the full day today. I need something like this for relocating the flash parts because they are tightly fitted within the motherboards. -- Roger http://www.eskimo.com/~roger/index.html Key fingerprint = 8977 A252 2623 F567 70CD 1261 640F C963 1005 1D61 Tue Apr 10 20:10:37 PDT 2007

I don't have an account so I guess I can't edit the wiki, but anyone can feel free to add the stuff, or if desired, I can work up something and submit it for consideration.

I imagine it is something that people have already done, but have been too embarrassed to post. ( I, fortunately, have no shame ). It involves taking the little push tacks ubiquitous in the office environment and clipping off the needle point. I then super glue them to the top of my flash (I only recommend this for PLCC. With DIPs, and whatever else, you are probably better off with the chip pullers). Pictures of my experiments are shown here; > >> > >> http://members.cox.net/rtphilipson/knob1.jpg > >> http://members.cox.net/rtphilipson/knob2.jpg > >> > >> So far it has been very successful. I have not had a knob fall off (yet). With the PLCC I think this is a much safer way to hotplug than using a chip puller. If I ever do have one fall off, I'll have a future post about recovery techniques :o). The most important point is to shave off the resulting nub left when cutting off the needle point so that you have a flat surface to glue. I recommend a dremel tool grinder. Although I've had success using a scissor blade (takes a long time). If you have a BIOS sticker on top, you'll need to peel that off and clean off the glue thoroughly. > >> > >> One of the drawbacks is that the chip part number is covered up.
