I think you can still find "Serial ATA AHCI BIOS" on Intel site. You need to find Intel mobo with same ICH7 as yours. (I guess, any ICH7 will do) Download its BIOS and analyze it using AndyP tool - it’ll extract all modules. Than search for one with "Serial ATA AHCI BIOS" string inside. We have used very same approach to get latest SATA RAID BIOSes. And you are right, ICH should be already in AHCI mode to BIOS to pick it up. All stings from ICH8AHCI.BIN: Serial ATA AHCI BIOS, Version iSrc 1.20E Copyright (c) 2003-2008 Intel Corporation ** This version supports only Hard Disk and CDROM drives ** Please wait. This will take few seconds. Controller not found Controller not set for operating in AHCI mode System Error Memory not available AHCI BIOS not installed No device found Error in accessing HBA memory-mapped registers No area available for Command List/Command Table/FIS Controller in RAID Mode System BIOS does not support BBS Device initialization error Identify device failed Invalid device geometry Init device parameter failed Recalibrate device failed SMART command failed Device verify failed Port reset failed SMART event logged (Device not supported in this AHCI option ROM build) (Drive is controlled by the RAID BIOS)
AndyP tool can extract modules from *.BIO files? didn't know that. Could be possible that for ICH7 did not exist such AHCI BIOS oROM. Some time ago I search a lot of time but for ICH7 family only SATA RAID oROM was all I can found. Today I receive one SATAII expresscard I'll try to find if I can boot from that card if yes then will modd this to make simple or RAID system My bad luck I don't have esata cables right now.
Might be. It’s strange the one you found doesn’t support it, but ESB2 Could Intel have another AHCI BIOS line for ICH7, ICH6, ICH5, etc? I don’t even remember how ICH6 related to ESB2 Once you do it, there won’t be any need to continue this thread, right?
Right. And you card is HDD, isn’t it. According to PCI spec, BIOS should “scan/execute” AA55 segments (oROMs). And it does – you won’t see Sil3132 menu otherwise… Ok. But it won’t boot from it anyway, right? Strange… So there is no any BIOS menu on your notebook where you can set boot devices search order and enable/disable them? BTW: Check Dell DCCU report - what BIOS settings does it see?
That is on most other bios but in case of Del especially notebook maybe not since you can't add all kind of hardware.I see Sil3132 menu becauseI force loading There is a menu for boot order,I can change order and enable disable floppy hdd dvd and network but Sil3132 is loaded later that could be the problem Maybe BIOS is looking for oROMS but only where he expect to be,something like module id,and if find then is loaded.
So if you replace PXE oROM with Sil3132, it just show RAID menu but won’t boot, even if you select network boot first, right? Yep. If BIOS has modules with ID, id does load based on ID. So if you replacing PXE oROM with Sil3132, you need to keep same module ID. It won’t find it otherwise. At least that’s the way I did it with GX620 (and got unsupported hardware) I guess, you did it very same way. About network boot… I don’t know how BIOS tell what is network and what is HD. I guess, it might be some flag and most likely changeable.
Yes. I keep same module id. Maybe BIOS know to load some oROM's in initialization stage but only if they have some id for what BIOS is looking
I have replaced inside BIOS Intel VGA ROM with oROM for SIL3132.Now if card is inserted oROM is loaded by BIOS itself,is loaded before choosing boot device (if I press F12 to choose boot device,first is loaded SIL oROM then is presented boot menu,but still no available in this menu.) I was playing with kexec-loader but seems some problems to load ntfs module.
I have read the entire thread and have downloaded Andy's and Apokrif's tools. I am trying to decompose the BIOS for a Dell PowerEdge T110 found on the Dell site. (Can't post a link yet as I have just started using MDL). I extracted the header file and when run through Andy's tool (Phoenix Mod Tool 1.42) it "works" for a while and then errors out saying: Error 9 - Index was outside the bounds of the array. The results before this error happens are: Dell BIOS $RBUT at 0 Block at 54 Block at 1054 Block at 10054 Block at 11054 Block at 40054 Block at 70054 Block at 71054 Block at 115054 Block at 340054 Block at 390054 I also tried to run the hdr program from Apokrif's tools but don't know how to specify the hdr.ini entries for this machine. I have: [PET110-010304] 00054C0D0054 When running hdr with the L command it scans at various xyz54 boundaries and I get: file length 40005C -> scanning for CRC32... scanning 004054 scanning 008054 ... scanning 3FC054 crc32 found at 400054 whole file: crc32 found at 400058 section start 0x000054 Any help in decomposing this BIOS into modules and uncompressing them is greatly appreciated. Thank you Subu
Sebus: I just want to understand the various components of the BIOS; how they are structured and linked, what compression routines are used and how to put back the BIOS together. I also have access to IDA Pro and am new to reverse engineering. Subu
Thank you very much. It's for Service Tag: FZX6FN1 for a Dell Poweredge T110 BIOS version 1.3.4 dated 6/18/2010. This BIOS seems to support both the legacy BIOS as well as an UEFI BIOS (selectable in BIOS setup) The URL is: support.dell.com/support/downloads/format.aspx?c=us&cs=08W&l=en&s=bsdv&deviceid=11809&libid=1&releaseid=R270563&vercnt=4&formatcnt=0&SystemID=pwe_t110&servicetag=FZX6FN1&os=LHS64&osl=en&catid=-1&dateid=-1&typeid=-1&formatid=-1&impid=-1&checkFormat=true Thank you Subu
After many tries I've managed to load OROM from card itself. (Card was without flash chip,so I solder one and program but OROM was 128K and flash chip was 256K,at first sight no matter but after reading datasheets and checking registers I see that OROM was not loaded from card because SIL3132 chip was looking for signature at the end of flash and since size was different that signature was in middle.) Now with original bios (nothing altered) OROM is loaded from card but no way to boot from that card. Card expect BIOS to handle process of booting, maybe if I can find other vendor who use same chip but have OROM who can boot itself, no matter what BIOS do. That such thing exist? Also a little annoying thing is that RAID device is "removable device" under windows. I found something related into DSDT and removed now under other OS's there is no sign of PC Card like before but still partitions are see as "removable device" For the moment I can boot windows using XP kansas City shuffle method from 911cd.net
D620 Bios mod I`m a newbie on this forum so i`m asking the following maybe someone can help me.I have a dell latitude with a nvidia graphics card and i want to mod its bios DSDT table.Can someone help me with a short tutorial on how to do this or with some advices.Untill now i`ve been able to extract the DSDT from the bios using a linux live cd and also to extract from original bios the hdr file.But i don`t know how to decompress it.
