答复: [COMMIT] romcc 0.63 and some fixes...

I'd like to wait it to produce smaller code. Otherwise if I enable superio + ati support, It will be greater than 64K in debug mode. When will that be ready?

Testbios works for ATI too !!!
by Li-Ta Lo 28 May '04

28 May '04

Hello, I just tried my "imporved" testbios on ATI 9800PRO under LinuxBIOS. It can init the card. The only problem is that the normal BIOS store the PCIDEVFN at some bytes in the C segment so I have to change the vbios.bin a little bit. I will commit the current testbios into V2 tree after doing some clean up. Ollie

Hello, I'm new to: This List, and Linux in general. Why I joined: I have a keen interest in both Linux and BIOSs, and may be able to provide some help on the BIOS and hardware end of things. Some about me: I work for a company that provides "aftermarket" Award BIOSs, built from source provided to us through an agreement with Award themselves. I'm a semi-recent graduate of Electrical Engineering, and live in Massachusetts. I actually concentrated in embedded systems design, but I ended up here, configuring BIOSs, and working on the company website, go figure :) I thought I might be able to provide some help on the hardware side of things, having a lot of insight into the BIOS. Obviously I can't share the source code we have, or violate any of the agreements my company has though. This list seems fairly busy, from the few mails I've already received today since I signed up. -Jesse

Questions about Quartet build
by maillists＠petrolhead.com 28 May '04

28 May '04

Hi, I've been trying to understand mp_table.c and irq_tables.c for the Quartet, these files don't seem to match the Quartet architecture and I'm a little bit confused as to why. My questions regarding these files are; 1) It appears that these files are expecting certain 8111 devices (PCI bridge, LPC bridge, etc.) to be on PCI bus number 1. Shouldn't they really be on bus number 0? The Linux BIOS seems to enumerate this as bus 0. 2) The code in mptable.c looks for the 8111 on bus 1 and so would default bus_8111_1 to 4 and bus_isa to 5. Bus 5 conflicts with the enumeration of the second 8131. Is this correct or should it just be looking on bus 0? 3) Is bus_8131_1 and bus_8131_2 supposed to represent both PCI bridge devices within a single 8131? I can't see anywhere in the code where it fills out the MPS table for the fixed devices like the inbuilt NIC or SCSI. Many thanks for the help Chris

答复: 答复: 答复: Getting Started with freebios2!

So the LinuxBIOS need to 1. init USB controller 2. create usb_dev to be serial. 3. use usb_control_msg and usb_bulk_msg to talk with the serial device. What the USB type, OHCI or UCHI or EHCI?? I wonder if some source code or documents that define No 3 above?

USB support status: For OHCI (AMD8111) support, it can do ED-TD process well. Only one problem left: When it using bulk transfer (ed 1 and 2) to talk to the USB disk, it gets the USB ERR 5, that means device does not response. But control ed (0) works well, can get the USB disk serial number.

Run ``readelf -h -l'' on the problem image to see what the values are before it is combined into LinuxBIOS. I suspect you have a build problem, possible a messed up version of perl installed.

Iwill DK8S2
by Hendricks David W. 27 May '04

27 May '04

I'm committing some new stuff for the Iwill DK8S2 mainboard to replace the old stuff in src/mainboard/Iwill/DK8S2. I'm also adding a targets/Iwill/dk8s2 directory. Looks a lot like the HDAMA, but some tweaking is needed and VGA has not yet been tested, I'll look into it further today. So far I've tested it and it boots into Linux.
