I upgraded the computer with an edo 32mb-module. The memory counter in dos counts up 36mb, cuase it already have 4mb built in.

But, in WIndows it shows just up 16mb ram. What's wrong?

another question, is it possible to use a bios overlay in order to get full-size from a 6.4gb's hdd? Right now i have just 120mb, ant its too small and too slow.

Thought that i would get out with this old thing and surf on the www

If the BIOS detects the RAM, then most likely, your OS isn't set up properly.

As far as hard drive goes, yes, you can use an overlay, but you'll have to set up the overlay with the drive in a computer with BIOS support for that hard drive. Once you install the overlay, you can take the hard drive out of that and install it in any other computer.

I followed the instructions from this link. http://www.thinkpads.com/6gig-limit.htm

But i didn't installed Win95 directly after that.
However, the low-level format seems to work. And bios finds a small disk that in fact is big (when i boot from disk-manager floppy). But when i breaks the power and try to boot up.
I always get a error message about the hdd. It seems like i have to boot up from the diskette first always.

Do you know what I'm doing wrong?



I bought 2X64mb EDO-ram which i will recieve soon in the next week. And try to see if the TP can handle one of them.
t. But i doubt that it's possible for TP from late 1993....

It works good to boot up the computer with the Diskmanager-diskett in it. Even also when I press ctrl+alt+del. and the computer recognizze the drive to be a 52Mbs drive.

But I always get up the error messeage "1790 - harddriverror" when I tries to make a clean bootup without the diskmanager- diskett.

Can the computers empty cmos battery cause that it never "remember" the new hdd-size, when i make a clean bootup?

I thought that i don't would need to boot from the diskett everytime. Are I wrong?

1790 Diagnostic cylinder read error (drive 0)

What to do, is it something i can fix with diskmanager?

I finally got the new hdd to work in it.

But windows continues to only recognise 16mb of ram althugh Bios finds 36mb which is correct by the bios. (I have reinstalled the OS)

The memory-issue is a big pain in the [censored]. But, bought a single 64mb module which i will try with when i get it.

Anyway, its a cool but slow very slow laptop.
Tried to browse the internet on it with 0.5 mbs DSL. IT worked very well. The only problem is that it takes a bit time to scroll on the pages

I used IE 5.5 and Opera 7.x or 8.0. (Dont remeber which of em.)

My dsl-connection is good for about 55kb/sec. But the computer came never up in more than 33kb/sec although i tested to download from a server which i know is a lot fast. Maby the slow cpu keeps down the speed.

I dont think the speed would increase if I buy a faster hdd with larger cache. The disk seems to have to wait to deliver to the slow cpu all the time.

Well, this disk made the compputer a bit little bit fasten than with the old one. The old one was both VERY noisy and small. (not the sound from the read-head, but from the spinning sound which appaear all the time)
