[LinuxBIOS] #88: Add UHCI/OHCI/EHCI support to GRUB2

#88: Add UHCI/OHCI/EHCI support to GRUB2 ---------------------------------+------------------------------------------ Reporter: uwe | Owner: somebody Type: enhancement | Status: new Priority: major | Milestone: Port GRUB2 to LinuxBIOS Component: code | Version: Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ As per http://www.linuxbios.org/pipermail/linuxbios/2007-August/024059.html: {{{ > > FILO can already do usb/el torito cdrom boot, but it badly needs > > ehci support. > > The FILO USB stack is not completely robust as I've understood > things. AFAIK it also only supports OHCI and neither UHCI nor the > quite desirable EHCI. UHCI is there. But I think the stack never worked except embedded in etherboot. If anyone wants to make a grub2 module out of it... ;) }}} -- Ticket URL: <http://tracker.linuxbios.org/trac/LinuxBIOS/ticket/88> LinuxBIOS <http://www.linuxbios.org/>

Re: [LinuxBIOS] [RFC] Call for Action: LinuxBIOS foundations
by Robert Vogel 30 Aug '07

30 Aug '07

Very Strange. I didn't write the note attributed to me (below). It's not clear where it came from. I'll comment on it though: It LinusBIOS is licensed under GPLv3, it is my understanding that there are good protections against Tivoization. Also if the code is fully disclosed I think that there is considerably less possibility of treachery. That's why I think it could be better at home. The question that I asked...which I'm stilling searching for an answer: If there are one million computers running LinuxBios, are they dedicated to server farms ? ...or can they be used as desktop machines ? Looking at http://linuxbios.org/Products most vendors are configuring clusters and it is not clear if anyone offers a desktop machine. The FSF says that it is working on one. Are there any vendors that will attempt a desktop machine with LinuxBios ?

[LinuxBIOS] resend: [2/5] Open Firmware on LinuxBIOS on M57SLI

A trivial one-liner for the CPU I happen to have. The sales docs said it's a "G1 revision", but the Rev F code works just fine. Signed-off-by: Torsten Duwe <duwe(a)lst.de> Recommendation: please apply.

[LinuxBIOS] Flashrom

Today I retry to add support for the Winbond W29C040P chip. But read theams work not correct. I look into the files with "hexer" it look so much different from a Epia Cl save. The Target is a Compaq T30, it is a thin client with a Geode GX1. I append the bios save. Can anybody say if this is ja possibel file? Greeding Markus
