EPIA + CONFIG_VGABIOS works
by SONE Takeshi 22 May '03

22 May '03

Today I tried CONFIG_VGABIOS. After a little bit of config hassle and fix to compile error, it just worked. Now I don't have to use ADLO. I put VGA BIOS in flash rather than enablnig PCI option ROM (it was just 0xFF 0xFF..). I like this code, it is great development. I should have tried this one first. -- Takeshi

Is it legal to disassemble the proprietary VGA BIOS to learn how to enable a particular VGA chip? Of course, he (who?) will not copy any bits from the copyrighted code, he'll just pick up register addresses and values, and its order. If he would eventually write a code to enable VGA this way, can we share the resulting code? -- Takeshi

brun_mtd

Hello, In the script of src/util/mtd/burn_mtd there are these lines .. - dd conv=notrunc conv=sync bs=65536 if=${linux} of=vmlinux.bin.gz.block With this we if exist we don't trunc and fix the size of vmlinux.bin.gz.block, if it's more smaller than 65536 we put 0 until this size. - dd conv=notrunc conv=sync bs=63k if=${linuxbios} of=linuxbios.block The same but with 63k. - dd conv=notrunc if=docipl of=/dev/mtd0 We write without trunc /dev/mtd0 with the source of docipl. - dd conv=notrunc if=docipl of=/dev/mtd0 seek=1 The same but this time we skip 1 block of "bs" (i supose that we can remind the value of bs in the last line, then sizeof(docipl) ). - dd conv=notrunc if=linuxbios.block of=/dev/mtd0 seek=2 Without trunc we write linuxbios.block to mtd, skipping 2 times the last size (sizeof(docipl) ). - dd conv=notrunc if=vmlinux.bin.gz.block of=/dev/mtd0 seek=128 Now without trunc write vmlinux skipping 128 times the size of linuxbios.block. My questions, are: Why we write two times docipl ? And why we skip 128 times the size of linuxbios.block ? (i supose that i'm wrong, any one can help me with these) Thanks a lot for your patience.

Passes RAM test, but hangs at jumping to RAM
by SONE Takeshi 22 May '03

22 May '03

What could be a problem when it passes RAM test but hangs immediately after jumping to RAM? I'm developing a new raminit code and this happens only with a particular installation of DIMM. DIMM itself is not bad, it works when move to another slot, or another slot is filled with another DIMM. Award BIOS runs just fine with this DIMM installation. LinuxBIOS-1.0.0 Thu May 15 07:27:04 JST 2003 starting... Enabled first bank of RAM: 0x10000000 bytes Testing SDRAM : 00000000-0009ffff SDRAM fill: 0009ffff SDRAM verify: 0009ffff Done. Testing SDRAM : 00100000-01000000 SDRAM fill: 01000000 SDRAM verify: 01000000 Done. Copying LinuxBIOS to ram. Jumping to LinuxBIOS. (hangs up here) -- Takeshi

Anyone know the current status of running XFree86 on the Geodes? I'm currently looking at working on getting the VSA running on the Geodes as a BLOB. Anyone else started on this yet? --Bari

I'm going to look at doing that over the next week or so.

How to get technical information?
by Peter Busser 20 May '03

20 May '03

Hi! I'm sorry if this is a FAQ... How does one get technical information from chipset manufacturers? I have searched the SiS and VIA web sites and found no documentation or pointers to documentation whatsoever. Or am I simply not looking well enough? Groetjes, Peter Busser
