I have a similar problem with the EPIA-M (latest CVS): Initializing PCI devices... PCI devices initialized totalram: 127M Initializing CPU #0 Enabling cache... Setting fixed MTRRs(0-88) type: UC [hang] Is this due to the 128MB stick I am using? It seems to get recognized though. Stefan

Mini-ITX
by John Hearns 28 Jul '03

28 Jul '03

I've been off the linuxbios list for some time. I see there are a few threads on mini-ITX. Can I ask for some pointers to ROM images for EPIA-800 and M10000 Nehemiah boards (I've just got one on order) I see the ones on cwlinux.com - which specific boards are these for? Thanks!

Linuxbios and Via M10000, where to start?
by Barbini Uberto 28 Jul '03

28 Jul '03

Hi, I'm sorry for the quite trivial question, but I cannot be able to found it by myself. I have a via M10000 motherboard and I'm using it with gentoo with kernel 2.6.0.test1 and xfree86 latest snap, and acpid for clean poweroff by power button. All works fine, and I'm quite an happy user. I'm wondering if I happiness can grow still more using linuxbios to cut off booting time. ;) But is there any risk I cannot be able to run the above software? (first question) I'm not sure what I'm supposed to do, after downloading freebios, but I'm unsure of its function too. In the donwload page of linuxbios.org there is a link to "other software", I have to download that too? I'll be grateful for any hints and I apologize if this is not the right place to ask for it. Bye Uberto Barbini

Re: Fixes for Tyan s2880

Ron, It seems that you roll back to the tree, because of Stefan's complain. I want to give detail description on the coherent_ht.c and raminit.c 1. coherent_ht.c add two function: notify_bsp_ap_is_stopped. And wait_ap_stop. 2. raminit.c change csbase counting methods. Any way you at least can put files on s2880 for me. Also please send the Config.lb to me and I would to test the new config tool. Thanks. Regards Yinghai Lu -----邮件原件----- 发件人: ron minnich [mailto:rminnich@lanl.gov] 发送时间: 2003年7月24日 21:31 收件人: linuxbios(a)clustermatic.org 主题: Fixes for Tyan s2880 Yh Lu needed to add a mainboard-specific initialization code for the Tyan s2880 board, and needed it called at a special place in hardwaremain(). In V1, we would use defines and other such trickery to get this capability. We're trying to avoid that in V2. This problem turns out to be a perfect use for the static device initialization support. First, we apply patches that are tyan-only or are bug fixes to these files: src/include/device/pci_ids.h src/mainboard/tyan/s2880/auto.c src/mainboard/tyan/s2880/Config src/mainboard/tyan/s2880/debug.c src/mainboard/tyan/s2880/failover.c src/mainboard/tyan/s2880/static_devices.c src/mainboard/tyan/s2880/tyan-fallback.config src/mainboard/tyan/s2880/tyan-normal.config src/mainboard/tyan/s2880/VERSION src/mainboard/tyan/VERSION src/northbridge/amd/amdk8/coherent_ht.c src/northbridge/amd/amdk8/raminit.c src/southbridge/amd/amd8111/Config src/southbridge/amd/amd8111/Config.lb src/southbridge/amd/amd8131/amd8131_bridge.c targets/tyan/s2880/Config.lb Now, we need to ensure that YhLu's "special code" is called for his mainboard. As it happens, the mainboard is also a "chip" in the new scheme. The config tool builds a tree based on this structure, from src/include/device/chip.h: struct chip { struct chip_control *control; /* for this device */ char *path; /* can be 0, in which case the default is taken */ char *configuration; /* can be 0. */ int irq; struct chip *next, *children; /* there is one of these for each INSTANCE of a chip */ void *chip_info; /* the dreaded "void *" */ }; The tree for the s2880 looks like this: ===== #include <device/chip.h> struct chip static_root, static_dev1, static_dev2, static_dev3, static_dev4, sta tic_dev5, static_dev6, static_dev7, static_dev8, static_dev9, static_dev10; #include "/home/rminnich/src/bios/freebios2/src/mainboard/tyan/s2880/chip.h" struct chip static_root = { /* mainboard /home/rminnich/src/bios/freebios2/src/mainboard/tyan/s2880 */ .children = &static_dev9, }; struct chip static_dev9 = { /* cpu /home/rminnich/src/bios/freebios2/src/cpu/k8 */ .next = &static_dev8, }; . . . ====== (the rest is removed for clearness) Note that there are even "chips" for CPUs: it is possible to handle CPU fixup in this system. Each entry in the above structures defines a static device. Please recall that static devices consist of a generic structure and then special-purpose (device specific) structures. The generic structure is this: /* there is one of these for each TYPE of chip */ struct chip_control { void (*enable)(struct chip *, enum chip_pass); char *path; /* the default path. Can be overridden * by commands in config */ // This is the print name for debugging char *name; }; Device-specific classes are defined by the attributes of the device, and hence vary for each device. In the V1 days, we tried to have one generic structure, but that did not even work for the limited case of superio's, so for V2 we are making the structure unique to each device. We have to define one device structure for the Tyan s2880. The structure has to be defined in an include file that is in the directory that contains the code for the device. So, for the tyan s2880 mainboard, we need to have a definition file in src/mainboard/tyan/s2880. We'll call it src/mainboard/tyan/s2880/chip.h. In this case, it is rather simple: struct mainboard_tyan_s2880_config { int fixup_scsi; }; This is the only thing we're controlling at present. Note that the name of the struct is a 'flattened' version of the device name. We need to tell the config tool where to find the file containing the structure, and how to initialize the struct in the file. Add these lines to src/tyan/s2880/Config.lb. They will define the name of the file to use, and the code to initialize the static device. config chip.h register "fixup_scsi" = "1" We need to create the structure that defines the generic structure for the mainboard, so linuxbios can hook into it. So add these lines to the end of src/mainboard/tyan/s2880/mainboard.c: struct chip_control mainboard_tyan_s2880_control = { enable: enable, name: "Tyan s2880 mainboard " }; Then add the enable function (BEFORE the struct chip_control declaration). Note that it is declared 'static', and has only one entry in the switch. static void enable(struct chip *chip, enum chip_pass pass) { struct mainboard_tyan_s2880_config *conf = (struct mainboard_tyan_s2880_config *)chip->chip_info; switch (pass) { default: break; case CONF_PASS_PRE_BOOT: if (conf->fixup_scsi) onboard_scsi_fixup(); printk_debug("mainboard fixup pass %d done\r\n", pass); break; } } That's pretty much it. total changes are 170 lines. The static device tree (which is generated by the config tool, you don't have to write this code) now looks like this: ========== #include <device/chip.h> struct chip static_root, static_dev1, static_dev2, static_dev3, static_dev4, sta tic_dev5, static_dev6, static_dev7, static_dev8, static_dev9, static_dev10; #include "/home/rminnich/src/bios/freebios2/src/mainboard/tyan/s2880/chip.h" extern struct chip_control mainboard_tyan_s2880_control; struct mainboard_tyan_s2880_config mainboard_tyan_s2880_config_0 = { .fixup_scsi = 1, }; struct chip static_root = { /* mainboard /home/rminnich/src/bios/freebios2/src/mainboard/tyan/s2880 */ .children = &static_dev9, .control= &mainboard_tyan_s2880_control, .chip_info = (void *) &mainboard_tyan_s2880_config_0, }; struct chip static_dev9 = { /* cpu /home/rminnich/src/bios/freebios2/src/cpu/k8 */ .next = &static_dev8, }; ===== Note that the mainboard now has several new entries, and there is a new struct for controlling the mainboard, along with an initializer. The enable function for the mainboard will be called at several places in hardwaremain with a different pass #, and since there is only one case defined, only one action is taken. So to add this capability for this mainbard, we had to: - define a file containing the device-specific structure which we called chip.h, and placed in src/mainboard/tyan/s2880 - add two lines to src/mainboard/tyan/s2880/Config.lb, which define the file we need (chip.h) and the initialization of the structure. - add the "base class" structure to src/mainboard/tyan/s2880/mainboard.c, along with the enable function. I've built this mainboard and hexdump of the romimage looks pretty good. Yh Lu, can you please verify this? The config.lb is in targets/tyan/s2880/Config.lb. I can send the context diffs if that will help. Note that this technique will work for anything that the config tool considers a 'device': mainboard, cpu, north and south bridge, superio, etc. Thanks ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

I thought I succeed in configuring dhcp server. But I can't check if dhcp server is working right. are there any messages to be poped up when my epia found dhcp server? Another question............. After I succeed in configuring dhcp server, how can I tell server to load vmlinux.epia. I just made vmliuz.epia using mkelfImage tool. I'll gladly thank for any help......... I'm just beginner............ _________________________________________________________________ MSN Messenger를 통해 온라인상에 있는 친구와 대화를 나누세요. http://messenger.msn.co.kr

GA-7DXR
by Stefan 27 Jul '03

27 Jul '03

Some weeks ago, I wanted to know if my Gigabyte GA-7DXR is compatible with the LinuxBIOS, and ron asked my something about the serial, etc, written on the surface of the bios rom! Now, here's it: HYUNDAI KOR HY20F002TC- 90 0119A There was also a kind of sticker on it, on which was written: PhoenixBIOS D686 BIOS 006919492 I hope you can help me now, thx & greetings

Can you help me? I'm working on VIA-EPIA
by gimyung han 26 Jul '03

26 Jul '03

hi everyone !! I'm trying to burn romimage on the VIA-EPIA (VIA C3-800 Mhz, VT8231) I just succeeded in making romimage, and I cd into /freebios/util/flash_and_burn, and type make to compile. Finally, I got excutive file "flash_rom". To test "flash_rom", I typed flash_rom without any parameter. and I saw following message Calibrating timer since microsleep sucks ... takes a second Setting up microsecond timing loop 153M loops per second OK, calibrated, now do the deed Enabling flash write on VT8231...tried to set 0x44 to 0x54 on VT8231 failed (WARNING ONLY) Trying Am29F040B, 512 KB probe_29f040b: id1 0x25, id2 0xa6 Trying At29C040A, 512 KB probe_jedec: id1 0xbf, id2 0xb6 Trying Mx29f002, 256 KB probe_29f002: id1 191, id2 182 Trying SST29EE020A, 256 KB probe_jedec: id1 0xbf, id2 0xb6 Trying SST28SF040A, 512 KB probe_28sf040: id1 0x25, id2 0xa6 Trying SST39SF020A, 256 KB probe_39sf020: id1 0xbf, id2 0xb6 SST39SF020A found at physical address: 0xfffc0000 Part is SST39SF020A OK, only ENABLING flash write, but NOT FLASHING and then, I type "./flash_rom /root/epia/romimage". "/root/epia/romimage" is a full path of romimage I had made. I saw messges like below Calibrating timer since microsleep sucks ... takes a second Setting up microsecond timing loop 152M loops per second OK, calibrated, now do the deed Enabling flash write on VT8231...OK Trying Am29F040B, 512 KB probe_29f040b: id1 0x25, id2 0xa6 Trying At29C040A, 512 KB probe_jedec: id1 0xbf, id2 0xb6 Trying Mx29f002, 256 KB probe_29f002: id1 191, id2 182 Trying SST29EE020A, 256 KB probe_jedec: id1 0xbf, id2 0xb6 Trying SST28SF040A, 512 KB probe_28sf040: id1 0x25, id2 0xa6 Trying SST39SF020A, 256 KB probe_39sf020: id1 0xbf, id2 0xb6 SST39SF020A found at physical address: 0xfffc0000 Part is SST39SF020A I thought, romimage was burnt on my rom......... I reboot the system, buf nothing was changed............ What's wrong with my procedure..................... I did change original rom.............................. is it impossible to burn image on the original rom ? If so, What should I do? Please, give me your wise advice..... _________________________________________________________________ 책상위에 다리 올리고 느긋하게 즐긴다... MSN 온라인 상영관 http://vod.msn.co.kr

Maybe you are right, becase I can not see any update on s2880 dir. And can not get config.lb and chip.c that you prepare for me. Can you send those files to me?

Did something roll back? Or are you seeing the 24-hour sourceforge.net delay? ron
