Yeah, we pretty much do, but I think its actually down to bios version, you would need new Amibcp that is not publicly available anyway, maybe you can just try tinkering with setup_var/ru software and actually enable csm on offset 0x11E2 value 01 (enables csm only, with uefi and legacy all together) for the rest we need lost_n_bios help.
Amibcp Version 5.0
Hey. Following the story of yesterday, where I found a few versions of Phoenix BIOS tools while scrubbing on my HDD archives... I also found a few versions of the AMI BIOS firmware tools, which I guess are worth of archiving too.
*AMI.ROMUtils.v627.10. Now, this one is more interesting. As it's name says, it was taken from Core v627 BIOS sources, and has an AMIBCP which was especifically designed for v6xx ROMs, and has full support for stuff as HiFLEX and WinBIOS. I was able to edit with it a PCCHIPS M710 ROM, which otherwise was corrupted when edited with later DOSExtended AMIBCP v7.x. Check you can't insert or delete modules with these older versions of AMIBCP, so they included both AMIMM and AMIEMBED tools for module manipulation. AMIEMBED is more powerful than AMIMM, as it can full manipulate (extract and insert) the "SLAB" (RUNTIME) module. Looks like AMIEMBED actually works with older versions of the core... I was able to edit modules on BIOSes as far as Pentium boards with it.
*AMIBCP_v6.21_v6.24T. These are even older versions of the ones included in the v627 toolset above. BCP621 goes back as 1994, so it should be able to edit later 486 and Pentium ROMs (as long as the manufactured didn't something tricky to their codebase customization). Ofc them have HiFLEX and WinBIOS support too. As with BCP from v627 toolset, you can't manipulate modules from the application. For that you can try with AMIMM or AMIEMBED from the suppplied v627 tools.
Now, I tried AMIBCP v6.21 with a couple of ROMs I had at hand. These were dumped from 486 motherboards, a HiFlex from 1994 and a WinBIOS from 1995. Unfortunately on both of them I got the dreaded "ROM Header not found !" error when trying the "LOAD BIOS FROM DISK FILE" option. The same happened with 6.24, but I had tried that version before.
Thanks for posting these versions! 6.24T uses the HiFlex default instead of the Color default, and can edit the Hardware Monitor tab on BIOSes retaining support for WinBIOS and Hiflex client editing. It also doesn't have the I/O header error which a previous version of 6.24 non T had on here, meaning you can load a BIOS from within the program. 6.21 is very close to 6.24 and there isn't much difference between the two, aside from one being older and maybe slower. 6.24E is a dud and does not work, attempting to load a bios but then blocking you off from loading it with an Evaluation message even when the date is set back. Perhaps someone could remove the Evaluation block on 6.24E and W5.11E (posted here a while ago, broken and also evaluation) to get something useful out of them, especially as W5.11E is the only availible version of AMIBCP 5 on the Internet AFAIK.
In resume... Looks like versions of the BCP program specific to the core them are shipped, are truly needed to manage the ROMs produced by these codebases. Unfortunately, by checking the evidence, we can conclude these programs aren't retrocompatible at all (in a sense, that would explain why core v6xx roms get potentially corrupted when edited by the popular DOSExtended BCP7xx program, even if at first it looks like them were opened succesfully).
And these old versions are lost in time. People has been searching them for years and no one seems to have them. Probably the ones who could had them wiped their floppies as contract requeriment, as these programs are generally part of NDA kits, and aren't supposed to be distributed.
Said that, i have a set of the older BCP program, which still doesn't make use of that f*cking DOS4GW DOS extender, and also an AMIMM command only version. But them where made with core v6 in mind, i don't think them can handle older core versions.
These don't look like real screenshots, but some example made in a text editor. Also they could came from some manual or textbook. I mean, i know about this specific quest very well, and no one i know was successful to find these editor versions, except the ones i have (for CoreV6, not the ones you can find easily in BIOS mod sites. These are for CoreV7/V8/Aptio UEFI) which are too new according OP request.
Yes, some people follows their contracts religiously even if years happened and no one remembers them/them aren't under it anymore. Since no one was able to find these older BCP versions, this makes me think the same fate happened to them, and now them are lost in time. Unfortunate, but as they said... "Shit happens" (tm).
The oldest Windows version I have is 2.42. The oldest DOS version I have is 5.11E. It would be nice to get a hold of every version between 1.0 and 5.0, but I'm feeling pretty pessimistic about this. The odds are about as good as finding a MR BIOS image for the VLSI topcat.
I used to do a decent amount of BIOS modding back in the day. Not sure if I ever had the old DOS versions that everybody seems to be looking for. I might have some old backup CDs somewhere that may have some older versions.. but not sure if I would have even backed that stuff up or if I actually got rid of those CDs or not. This would have been back in '97 - 2001.
They may be happy to release the older versions of the tool since it isn't going to even work on newer motherboards anyway.Would even be cooler if they open sourced these early BIOS' so that they could be modded by us ?
AMIUCP is a utility that is used to pre-configure the Aptio Flash Utility (AFU). Users can insert and exchange the default command string and ROM image used in AFU to create a customized version of the utility. AMIUCP supports AFU v2.35 or AFUWINGUI v1.12 or later. 2ff7e9595c
