Options for TTAV BIOS on T41?

#1 Post by micrex22 » Sat May 19, 2018 10:03 am

I have a T41 that I just upgraded with 2 GB of RAM, and now I want to put a different wifi card in it. Of course the whitelisted wifi module thing has to be dealt with.

The TTAV BIOS for the T42 and below only comes in diskette. Should I just use a USB diskette drive them to flash the BIOS? The other alternative would be to hack the TTAV T43 .ISO and inject it with the older BIOS, but I don't know if that'll pan out okay--I don't want to brick the BIOS.

I don't know what to say ...
'cept that I found the following :arrow: :

OK colour me confused...

AFAIK TTAV BIOS (es) are for T43 only

Secondly, T41 and T42 share the same BIOS...

No-1802 hack works wonders on pre-T43 ThinkPads IME...

Correct, the T41/2 share the same BIOS along with other models, TTAV mentions that in that forum post here: https://www.bios-mods.com/forum/Thread- ... 4#pid28984

He did make a T40/41/42 BIOS mod (called T42-SLIC2.1_7U_no_1802) and the file reads as follows:
MOD BIOS 1RETDRWW (3.23) with SLIC 2.1 (LENOVOTP-7U) including also NO-1802 mod.

This release supports the following systems:
- ThinkPad R50, R50p
- ThinkPad R51 (M/T 1829, 1830, 1831 and 1836)(*1)
- ThinkPad T40, T40p, T41, T41p, T42, T42p

Note: (*1) Machine Type 2883, 2887, 2888, 2889, 2894 and 2895 of ThinkPad R51 family are not supported.
However, the .ROM is naked and does not have a bootable feature, which is why I'd either need to use IBM's diskette flasher utility or create a custom .ISO using the T43 BIOS flasher that does everything all-in-one from the bootable CD image. I'm just kind of lazy and timid, so just wanted to know how others deployed TTAV's T42 .ROM.

EDIT: I noticed TTAV's original post mentions "ThinkPad T41_T42_R50_R51_SLIC_No_whitelist.iso", so there -might- have been a fully formed .ISO at some point, but I definitely cannot find it and it probably has fallen off the internet.

EDIT #2: the advantage with this new BIOS is that you get SLIC and permanent no 1802

So I just went ahead and created an IBM flashing diskette The problem is... IBM does not use a .ROM to store the BIOS, at least for this flashing option, it instead stores the BIOS in a .FL1 file along with a bush of other additional .SHAs, presumably to check the file???

Therefore I'm not entirely sure where to take this. IBM also released a utility to flash the BIOS in Windows XPloder edition, but I have a feeling it'll also use .FL1.

TTAV has this tip but I'm a little confused by it:
Tip: It doesn’t matter if you have download and install Windows 7 RTM retail version ISO or Windows 7 RTM OEM version ISO. Just use the following commands to convert to OEM version:

copy IBM-LENOVO.XRM-MS to C:

and in a dos box execute this 2 commands:

slmgr.vbs -ilc c:\IBM-LENOVO.XRM-MS

slmgr.vbs -ipk [redacted--some sort of product key]
That's just regarding windows activation and nothing to do with flashing a BIOS.

EDIT: I just extracted the installer and it instead uses 1RUJ37US.IMG, so *presumably* I could replace that with T42-SLIC2.1_7U_no_1802.ROM? But then I'd have to install XP and there's still a possibility the .IMG isn't fully compatible with the .ROM causing a corruption.

*sigh*

So I got curious and decided to compare TTAV's T42-SLIC2.1_7U_no_1802.ROM and IBM's 1RUJ37US.IMG. I did find some similarities but there were a lot of dissimilarities. I also discovered some hilarious things about the IBM flashing utility #1 that it runs on IBM DOS 5.0, #2 it is illegally using a manufacturer's evaluation of Phlash16 that's not supposed to be distributed to customers. LOL! And #3 there's a lot of redundant repeated code, very messily made. This explains a lot of things though, especially why a lot of this mimics that of the PS/2-era utilities, because IBM is still using their same old DOS 5.0 code, and now Lenovo is too! Sheesh. While I had a good laugh though, I don't think the .ROM is compatible enough to just be slipped in underneath, so I will (later) need to investigate the TTAV T43 .ISO. But that has a few challenges I will outline, later.

You'll notice both the .ROM and .IMG mirror the "Not available" (insert device here). However, IBM's puts a bunch of garbage in between the text. That's basically the only similarity I could find. LOL @ the IBM DOS 5.0 being repeated so many times.

Re: Options for TTAV BIOS on T41?

#7 Post by micrex22 » Mon May 21, 2018 11:46 pm

Okay... so I compared both of TTAV's ROMs, and verified the T43 and T40/41/42 ROMs are very much identical.
Therefore I took the T43 .ISO and edited it with the T42 .ISO, the F.bat needed some changes (this is the part that I'm not 100% certain on but I don't think it's super necessary?)

I went ahead and burned my custom .ISO, after running (which it did almost complete--or maybe it did complete?) I got this thrown in my face with the system making the phoenix warning beep which is exactly what I was worried about:
Phoenix Phlash16 Error
Undefined error number -28640
RESTART SYSTEM WITH CRISIS DISKETTE
I just powered off the T41, powered it back on and it 'seems' to be working? The IBM BIOS states that the 1RETDRWW 3.23 BIOS is now present, I don't get a wifi whitelist issue and whatnot. OS/2 launches just fine.

Is the system still running bits of the old BIOS? Or... what? I'm glad that the mobo is still working because I would have been so heart broken, but I also don't want the system to just unceremoniously die now.

EDIT: if this is too over everyone's heads, perhaps I should see about sending TTAV a message directly and get the proper ISO? The older modded T4x BIOS (pre-T43) should have been kept preserved, anyways! I don't know how it was missed by everyone's radar. At any rate I think the T41 is still fine despite the failure of the BIOS flash. I'm surprised it's still running, but I guess if enough of a BIOS flashes through, it'll still operate? Hmm.

You can also check the (T42) BIOS with SLIC Toolkit if it now has Slic2.1.
I never had a T40/1/2, only T43, otherwise I'm sure I would have had something usable here.

Well I'm going to try and get the actual image. If that fails I mean... my modded one (despite failing) does seem to work... despite horribly complaining near the end of a CRISIS.
Once I get all of this rounded up it'll be uploaded to my website. I just get sick in my stomach when important software goes missing.

Hey Dom (& George)!!! GUESS WHAT! I just re-read the ending bits of that forum in greater detail, and look what it says:
cyberpark: "It has stopped flashing at last. so I have to shutdown power and being preparing phoneix recovery disk. but when the laptop is turn on, it turn on correctly without problem and accept other wifi card."
TTAV134: "The flashing error message is useless, forget it."
So... it appears the flash failure is an expected behaviour when flashing the T40, T41 and T42 with this custom ROM, but it will end up flashing perfectly fine in the end--since I had the same end result as cyberpark (although I never bothered with the phoenix recovery diskette).

Therefore it looks like my rebuilt .ISO is in fact a success. I'll be publishing it later, I might even create a thread with all of these resources on T4x so it's all in one place and people know what to do. Granted I guess nobody cares much for a T42 and lower when there's the T43, but sometimes you might be gifted a free T41 ;)

I'm sort of wondering at this point how many people used this BIOS since everyone who has used it would have encountered this (and it would be quite the shock). I suppose so few downloaded it and burned it on that... it's sort of remained an enigma. I'm guessing the majority used the 'soft' fix for the whitelist problem? Of course you don't get SLIC but whatever.

I've learned a *lot* in this thread, thank you micrex22... :thumbs-UP:

Not to mention the fact that there's actually a T42 on its way to me as I'm writing this...time to tinker with it seems to be coming soon.

Well I've learned a lot from yourself and RBS over the years myself. I wouldn't have done some of my crazy ThinkPad mods otherwise!

I've uploaded the T40/41/42 BIOS, and the download URL can be found here: https://forum.thinkpads.com/viewtopic.php?f=2&t=126293

UNfortunately the rest of the TTAV BIOSes seem to be lost just as the T40/41/42 gets recreated, lol.
