by mount me 01 Dec '03

01 Dec '03

Hi linuxbiosians, Heard and Read that Windows 2000 can be booted using Linuxbios. Keeeeeeen and Interested in entering linuxbios. Could i get the list of OS's booted using LINUXBIOS and a brief explanation document along with it ? or links plz.... I am stilll looking for a motherboard in Chennai,INDIA Has anyone tried linuxbios in CHENNAI,INDIA ? need your support to start linuxbios with.

hdd register and dma
by Felix Kloeckner 31 Aug '03

31 Aug '03

hello, i am booting linuxbios from compatchflash and skip initialization of my additional hdd for faster booting (using kernel-commandline-argument "hdc=none"). after the system is up I register the hdd using #hdparm -R 0x170 0x376 15 /dev/hda everything works fine, except after enabling the drive this way I can't put it into dma mode, hdparm produces error like this: # hdparm -d1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) I am using elitegroup/p6stp-fl, sis630, sis5513 as IDE-controller any idea ps.: Bari Ari, did you find any solution to your "ide-hotswap" problem, please let me know! thanks Felix Kloeckner

Infrastructure status....

I have been working on merging the static and dynamic device trees, and I finally have a working version. The hard part was that I was enumerating hypertransport first thing and that was new code so any bug there and nothing looked like it was working. I have just a little bit more to finish up my initial superio example and then I plan on committing the code. I have had to extend the dynamic device tree in a couple of ways to get this far. Unless someone has some objects my plan is to tag the tree so it is possible to look back and then commit everything. There are lots of places where I am certain things can be done better but the code is far enough along to be useful. Which means it is now safe to put more eyes on the code and see how things are going. Eric

re: Unified setup...

Stephan, I have checked the AMD sheet, and you are right it will not change to setting width and speed without reset or LDTSTOP_L. In the pci_device.c, there is some code about HT. I have removed the hardcode about width and speed and do some test, after I checked the REG, and it seems width is set right but the speed is not right. Maybe Eric need to check that part. PS: - PCI_ADDR(0, 0x18, 0, 0x94), 0xff0000ff, 0x00ff0000, + PCI_ADDR(0, 0x18, 0, 0x94), 0xff0000ff, 0x00050000, [..] - PCI_ADDR(0, 0x18, 0, 0xd4), 0xff0000ff, 0x00000000, + PCI_ADDR(0, 0x18, 0, 0xd4), 0xff0000ff, 0x00030000, should be there. It defines the bus number behind the links. It will be used when enumerating the non-coherent devices.

Hi again, the coherent_ht.c changes are all to LYH's hardcodes to coherent_ht_finalize(). These are there to setup link speed and width on the cht nodes. I remember tomz from LNXI was working on that on a higher level at pci setup. Is that code complete by now? Are all bridges set up full speed? Then we could just drop this code, which i would favour. Otherwise it should walk into the motherboard specific code. As far as I can see this code is noop anyways since speed changes need a reset or LDTSTOP_L which is not asserted here.

about VGA support in voyager2 board
by elife elife 29 Aug '03

Hi, I am trying to add VGA support in cocom voyager2 board. The VGA is found but lb complain "biosint: Unsupport int #0x6" endlessly. I dumped the original bios and found besides VGA BIOS I extracted, there is VSA driver. Is VSA driver also needed to work with linuxbios and VGA BIOS? If so, Where should I put it? And need I do more things to make it work?

Stephan, All about the duplicate code are for the multilink etc. I think after Eric and the code to enumerate the HT belongs to the CPU0. and make the static links to work in chip.h and ... it will be eliminated. (auto.c and pci_device.c and cpufixup.c may all need the static config processing code) Regards Yinghai Lu -----邮件原件----- 发件人: Stefan Reinauer [mailto:stepan@suse.de] 发送时间: 2003年8月28日 6:34 收件人: linuxbios(a)clustermatic.org 主题: Unified setup...
