R40 P-M upgrade

[thinkpadcollection]

Chances there is modified bios to support dothan 400fsb 2MB P-M cpus? The voltages are same on banias and 400fsb dothan cpus. I use R40 for floppy work but XP starts up painfully slow on 768mb and 1.6 P-M plus intializing intel 2200 wireless takes long time. I had generic USB floppy drive that died, not again unless I must, get a brand name usb floppy otherwise tell me not to.

I had R52 that was sold to other owner who still enjoys it for video watching, but it is fussy with hard drive types, lucky I had one that worked. But not my taste, and I have a 15" R60/integrated GPU with dead board so need another board and heatsink if it is discrete GPU.

If there is one, nobody ever mentioned it on this forum, so I'd be willing to bet that there isn't.

There is a modded BIOS that addresses this issue.

I lost you here...what type of board are you actually interested in? The only thing that I figured out is that it needs to be for a R60...

Sorry. I meant needs either R60 15" integrated motherboard or 15" board with discrete GPU but needs heatsink to go with it.

Back on topic:
Is there a different non-intel mini-PCI card that has driver that initalizes faster than the intel Pro/wireless 2200BG that is already in that R40 I have right now? This 2200 thing initalizing and finishing booting to XP and responsive takes about 3 minutes appox. Also bios with wireless whitelist removed for this R40? This is last most powerful computer to support floppy feature.

Note that Dell D600 was one that supports *both* banias and dothan 400fsb CPUs, and have done them since I sold that to same owner years ago and had to repair twice, one to replace shot regulator PWM controller and one power transistor burnt to a crisp then on few years later swapped whole board later on (unrelated problem). That why I am looking at you "IBM" why we can't just easily swap banias to dothan 400fsb CPUs for 2 benefits: 3 watts less and up to 2.1GHz? This also support floppy caddy like thinkpad R40 does. Funny thing I now have 2 dells: D810 (P-M 2.26) and D531 (amd) also can use same floppy caddy as well but they are huge and heavy.

The R40 was not even made by IBM!
It was another mass-product from Acer, with a 'false' IBM-badge on it.
Because of that, nobody ever made any special BIOS-versions or other modifications.

The Intel 2200 always was (and still is) a decent wifi B/G card.
Yours is probably faulty, replace it with the same one, or get a PCMCIA wifi-card.

As for floppies: buy an IBM USB floppy drive, it will work on ANY laptop!
See e.g. here: http://www.ebay.com/itm/IBM-Lenovo-USB- ... 35de63908d
Once you have that, you could dump your R40, find a REAL IBM laptop and get on with your life...

I happen to have a R60 board with Intel graphics. PM me if interested.

No modded BIOS, but there's a "no-1802" hack which I presume has already been applied to your machine since 2200BG was not a factory option on R40. The best wireless card that you can put in there is this one:

Well, the same holds true for R5x and T4x series. You have to understand that R40 started as a P4M model and was only "upgraded" to PM boards at the very end of model's life.

There are no modded bioses for the R40 to support 400fsb dothans, unfortunately. I did some extensive research when I had mine and came up empty handed.

I did however conclude that the system could handle the chips and the only thing in its way was the bios limitation.
I bet if you went on one of the bios modding sites and bugged someone enough, or made it yourself (probably easier, trust me) , you would have a dothan in your R40 stable.

I also ran mine with a gig and a half of ram, it should be able to support a full 2 gigs. Head over to www.tweakhound.com and see his tweaking guides for getting the most out of what you already have, I highly recommend it.

As for your R60, I haven't looked into it any time recently, but I believe the 14" R60, 14" and 15" T60 and T61's use the same board. 15" R60's use a different board, and I made the mistake of buying the wrong one. I still have it around, but I'm not sure if it works or not. Make sure you get the right one if you plan on replacing it.
