Eric, Thanks for the quick response. >> 3. If enable RELOCATION: got error: It can not calculate the file size, and >> keep print " 61:rom_read_bytes() - skipping block 16" >The only difference in the loader that looks relevant >is the second PT_LOAD segment now has a size. >You are not running mkelfImage on the etherboot file are you? >That is only need for the Linux kernel. Yes, I didn't mkelfImage, I only use that to transfer kernel and add some tags, at last the ELF files is put into the boot server's /tftpboot. In the Config, You said that 5.2 need all drivers to support RELOCATION. So Does the E1000 driver support RELOCATION yet? Your snippet is for RELOCATION or not?

You can also make zelf if that helps. There was a naming cleanup in the extensions used by etherboot. > 2. If disable RELOCATION : got error: NO HEAP FOUND. Something is very wrong here even though etherboot got loaded. There are PT_LOAD segments. Etherboot only has one. Something looks corrupted. > 3. If enable RELOCATION: got error: It can not calculate the file size, and > keep print " 61:rom_read_bytes() - skipping block 16" The only difference in the loader that looks relevant is the second PT_LOAD segment now has a size. You are not running mkelfImage on the etherboot file are you? That is only need for the Linux kernel. > My Question is: > 1. When do you plan to support 82546? In 5.0.11 or 5.2.0. 5.0.x never. GigE drivers are to large, to easily support there. Plus the LinuxBIOS support isn't half as good in 5.0.x. =20 As for 5.2.x whenever there is enough consensus among the developers that we are there. We are quite close but... p.s. Someone remind me to put calculate the checksum on the etherboot image in apply_elf_prefix... > 2. Is there any easy way to modify 5.0.10 to make it work with Intel 82546? No. Here is a snippet of what the loader Loading etherboot should look like. ------------------------------ Found ELF candiate at offset 0 Loading Etherboot version: 5.1.8pre5 Dropping non PT_LOAD segment New segment addr 0x20000 size 0x21aa2 offset 0xc0 filesize 0x61de (cleaned up) New segment addr 0x20000 size 0x21aa2 offset 0xc0 filesize 0x61de Loading Segment: addr: 0x0000000000020000 memsz: 0x0000000000021aa2 filesz: 0x00000000000061de Clearing Segment: addr: 0x00000000000261de memsz: 0x000000000001b8c4 Jumping to boot code at 0x20000 ROM segment 0xdffe length 0xd050 reloc 0x00020000 >=20 > 222222222222222222222222222222222222222222222222222 > Welcome to elfboot, the open sourced starter. > January 2002, Eric Biederman. > Version 1.2 >=20 > 37:init_bytes() - zkernel_start:0xffff0000 zkernel_mask:0x0000ffff > Found ELF candiate at offset 0 > Dropping non PT_LOAD segment > New segment addr 0x20000 size 0x10e80c3 offset 0xb0 filesize 0x755c > (cleaned up) New segment addr 0x20000 size 0x10e80c3 offset 0xb0 filesize > 0x755c >=20 > Loading Segment: addr: 0x000000003ffca7e8 memsz: 0x000000000000ec0c filesz: > 0x00 > 0000000000755c > Clearing Segment: addr: 0x000000003ffd1d44 memsz: 0x00000000000076b0 > Loading Segment: addr: 0x000000000002ec0c memsz: 0x00000000010d94b7 filesz: > 0x00 > 00000000000000 > Clearing Segment: addr: 0x000000000002ec0c memsz: 0x00000000010d94b7 > Jumping to boot code at 0x20000 > ROM segment 0x0000 length 0xfbf8 reloc 0x00020000 > CPU 1343 Mhz > Etherboot 5.1.8 (GPL) Tagged ELF (Multiboot) for [E1000] > init_heap: No heap found. >=20 > 22222222222222222222222222222222222222222222222222222222222222222 >=20 > 333333333333333333333333333333333333333333333333333333333333333333333333 33 > Welcome to elfboot, the open sourced starter. > January 2002, Eric Biederman. > Version 1.2 >=20 > 37:init_bytes() - zkernel_start:0xffff0000 zkernel_mask:0x0000ffff > Found ELF candiate at offset 0 > Dropping non PT_LOAD segment > New segment addr 0x20000 size 0x1106000 offset 0xb0 filesize 0x76bcc3 > (cleaned up) New segment addr 0x20000 size 0x1106000 offset 0xb0 filesize > 0x76bc > c3 > Loading Segment: addr: 0x000000003ffca7e8 memsz: 0x000000000000ec0c filesz: > 0x00 > 0000000000ec0c > Loading Segment: addr: 0x000000000002ec0c memsz: 0x00000000010f73f4 filesz: > 0x00 > 0000000075d0b7 > 61:rom_read_bytes() - skipping block 16 > 61:rom_read_bytes() - skipping block 16 > 61:rom_read_bytes() - skipping block 16 > 61:rom_read_bytes() - skipping block 16 > 61:rom_read_bytes() - skipping block 16 > 61:rom_read_bytes() - skipping block 16 > 61:rom_read_bytes() - skipping block 16 > 333333333333333333333333333333333333333333333333333333333333333333333333 3333 > 3 >=20 > -----=D3=CA=BC=FE=D4=AD=BC=FE----- > =B7=A2=BC=FE=C8=CB: YhLu=20 > =B7=A2=CB=CD=CA=B1=BC=E4: 2003=C4=EA6=D4=C213=C8=D5 0:27 > =CA=D5=BC=FE=C8=CB: ron minnich; ebi...@ln... > =B3=AD=CB=CD: lin...@cl... > =D6=F7=CC=E2: =B4=F0=B8=B4: High-End Desktop Support >=20 > Eric, >=20 > I am working on porting linuxbios to Tyan s2725.
