Thinkpads Forum

Yes, the clock circuit was in "the other side" of the mainboard. I finally had today the time (and courage) enough for doing the hardware modification to my "very old" 600E to have it working at a clock speed of 100MHz and.... it works !!!!

I thought for a while in doing also the FSB to 108MHz mod, but the resistor I have (1/8watt) is too big for putting it under the MMC2 board and, aditionally, the solder I have, being small, it is not the appropiate for the places that have to be solded the resistor.

So, I'll stay with my 100MHz and now waiting for the new memories to come to my hands in the coming days (hopefully).

I just installed a new HDD on my Thinkpad 600x 4EU 500Mhz. Its a Samsung 120GB HM121HC for 44 Euro incl. shipping. It works without any problems out of the box. I cloned the old original 12 GB HDD with HDclone free edition. The new drive is basically silent in comparison to the old shaking and buzzing HDD.

My attobench results. Max at about 22 MB/s. My home SSD reaches easily over 100 MBs but thats another story.



For comparison my original 12 GB from 1999. Its about half the speed but with real working the speed improvement is much larger.



Another comparison with the TP 600E with the original 6GB HDD from 1999. Really slow with 4-6 MB/s max.

Uniter, i also decided to upgrade the HD on my 600x from the original 12GB to a new 40GB. I did a test on the old HD using the same software, 8-9 mb/s, pretty much the same as you were getting. Now i'm getting 20 read, and 32 write speed. (why the big difference in read/ write ) Its also a lot quieter.
Finally i upgraded the RAM to 448.

I'm wondering if a BIOS flash is necessary to get a large HDD working properly. My version is 1.09 and I installed a dual-boot but for some reason one of the OS' will not load. I also get a message before my linux boots that a forced ACPI will be done. It also says something about an old BIOS image (1999) and no (2000) BIOS.

Something along those lines. I'm assuming a newer BIOS version must be necessary to get my dual-boot working properly.

Possibly, but I don't know.

Note that the internal BIOS date of ALL 600X BIOSes is 1999, even though the release date for some of them was a few years later. The reason for this has to do with something about Windows 98 installation and the use of the BIOS date to determine ACPI/APM compatibility.

I'm not saying you shouldn't upgrade your BIOS, and maybe that will solve your problem. I'm just noting that you should be careful if you are relying on the internally reported BIOS date to make any decisions about this.

you guys are going to make me drag out a 600X and make an 850MHz version... dang you people

ok 600X check, CR2032 battery, check. can't find a battery... I know I have one, check. MMCII 850MHz CPU dang... 800MHz good enough

I have used the caddy and faceplate of a bad TP 600 UltraBay CDROM drive and replaced the bad drive with a DVD/CD-RW combo and it works just fine.

Hi,
Just preparing for LCD replacement and found helpful video on this, since I have two dysfunc and 1 working 600x (win7, 512mb ram, samsung hm160c hd) and I'm a little nervous about it.

Mom is giving me her old "A" series in July, but I need my winged turtle for now.
