Why 3.0GB, not 3.25 or even 3.5? [Updated with Answer]

[JaneL]

Lol, the forum admin had a weird requirement for creating an account. For some reason, the location was mandatory. I was trying to hurry and create an account, and the thing kept kicking me back for not providing a location, hence the BFE. Meant no disrespect however, since Egypt is on my one of the places to visit before I kick the bucket.

The forum owner and admins have zero sense of humor about the location requirement. Fix it now.

New sysrescue_grub2.iso posted. Now I disable that memory range (4 KiB) as well as reenable the 8MiB range I turned off earlier to play safe. The biggest surprise is that I'm getting the *same* error when I run memtest (except my EHCI controller was at d0504000). It's quite surprising I never experienced any crashes earlier - either that memory was never used or the faults were masked (never became noticeable errors). I still don't know what's causing the problem, but I wouldn't be surprised if it's because the USB controller can't be reconfigured after initialization.

I did see your memtest picture before they disappeared. I figured out how to boot memtest from grub2 and slipped it into sysrescue_grub2.iso. Run memtest again for a few minutes to make sure that error doesn't occur. Then try to boot Kubuntu or Windows.

[Uncle Joe]

OK, at least we eliminated the memory corruption problem and verified
that the former 8Mb RAM can be reclaimed. Since there can be so many
inconsistent settings due to the PCI remapping, I've inserted a call
to do a debug reset on the GMA 950, which claims to reset everything
to power on state (earlier, I just called a function to change the VGA
mode).

Get the new boot disk and see if it works. After the reset (during set
TOLUD phase), the display might not show anything if additional
initialization needs to be done. Let's hope that's not the case.

Hi All!

I got 15" t60p UXGA FLexView, with M/B rev03, which upgraded to 4GB, Core 2 Duo 4 and 500GB spinpoint M7. I saw this thread before buying, and was sure that there will be solution soon. (but sadly it now looks as inactive thread, with dead links).

I am using 64bit PLD Th-test, with grub2, and generally I am experienced linux user, but I am scared a bit with modding bios and uploading it. (if its stored in RAM, couldnt we replace[copy in RAM] it from grub to check if it works, and later after confirmation flash). Anyway I dont understand really on what hardware it works(Intel/nVidia), but I got FireGL V5200, and theres not too much about that, and what steps should I make.

And I also got horrible flex over the HDD, and theres much space after it, enough to put usb hub and media card reader, dunno if there are internal usb connectors, but I got only 3 USB ports external on laptop + 3 on docks. So its only 3 USB 1.1 root hubs, but lsusb shows 4 when docked, and one 2.0. Probably lasting two went to BT and FP, but this space is ideally under FingerPrint reader .
But I definitely want suspend to RAM working, its more important than addition 1GB.

Its mine hardware listings:
lshw output
lspci output
lsusb output
lspnp output
hal-device output
dmidecode output
dmesg output

[Uncle Joe]

evil,

Thanks for your interest. You might get better luck than jack_uta since you don't have i945 graphics, which I didn't figure out how to correctly remap its memory without corrupting the screen.

Based on your lspci output, I believe you can get 3.5GiB RAM. Send me your MTRR register values
(look in /proc/mtrr or dmesg)

You have to mod your BIOS to get this to work, but I'm pretty sure you can do a rescue from a USB floppy if needed. There seems to be 2 bios images for T60, so tell me the name (extension is wph). Just extract the BIOS update from Lenovo and just before doing the flash, see which image it's using. It seems if you're using 64bit Windows, you might have trouble identifying which image to use since you have to use a bootable CD to do the flashing (probably because Phoenix didn't port WinPhlash to 64 bit yet).

When I said my mod breaks suspend and resume, it only breaks when you enable the mod via Grub. You can always choose not to.

"Release Date: 08/27/2009" - WTF? (month/date/year?), and how its possible to obtain so new system with IPS/FlexView screen? (its second hand, bought month ago, but on Hong-kong box is similar date)


I definitely want to make this mod, but now rsget.pl is working, and I am not sure about result of killing it, so I can reboot to windows tomorrow and upgrade BIOS if its needed. I got only nearly-fresh 32bit XP, but upgraded to SP3. Should I make special rescue and run touchmem? (if it can crash current system, than definitely I will remaster rescuecd)?

I can try also to disable some devices in BIOS(like DOS USB support), if it can allow me to get more memory. If gfx card allocates another 128MB memor, then other devices should fit IMHO into ~16MB like in mine current 1GB 32bit system when setting very low vmalloc. Or am I wrong?

[khaverblad]

It's not that I'm stupid enough to have ignored all the warnings about the limitation and bought 4GB anyway. I actually called IBM support twice, once being told that vista can do 4GB (probably he's just reading off http://www-307.ibm.com/pc/support/site. ... MIGR-55644 , the other time being told that they are working on the issue and asking me to call back in a few weeks. Plus, I figured that all the stuff in T60 couldn't have taken up a whole GB and I might be able to use somewhere between 3.25-3.5, which isn't too bad...

Well, interesting...... [deleted]

Hello all,
I'm considering using the BIOS mod and Grub 2 code Uncle Joe has written.
I have a T60 2007-M3E with BIOS 2.25 (79ETE5WW) 2009-8-29 and Embedded Controler version 1.07.
The machine has an ATI X1300 with 64MB RAM. But when I run lspci it reports 128MB RAM. I'm guessing it just reserving that much memory, as it most definitely is only 64MB.
I'm a little confused about modding the BIOS. As to which version I should mod, and if following the instructions for modding the BIOS layed out in this thread would be applicable to it.
I don't particular mind losing sleep and suspend if it means I can use more of the 4GB of RAM the machine has installed.
When modifying GRUB should I treat the ATI card as 64MB or, as lspci reports, 128MB?

I have included a shortened DMESG and a full lspci output.
Any help anyone could offer would be great. I'm currently running Windows 7, so would be looking to use GRUB 2 with it.

DMESG

Hello all,
I'm considering using the BIOS mod and Grub 2 code Uncle Joe has written.
I have a T60 2007-M3E with BIOS 2.25 (79ETE5WW) 2009-8-29 and Embedded Controler version 1.07.
The machine has an ATI X1300 with 64MB RAM. But when I run lspci it reports 128MB RAM. I'm guessing it just reserving that much memory, as it most definitely is only 64MB.
I'm a little confused about modding the BIOS. As to which version I should mod, and if following the instructions for modding the BIOS layed out in this thread would be applicable to it.
I don't particular mind losing sleep and suspend if it means I can use more of the 4GB of RAM the machine has installed.
When modifying GRUB should I treat the ATI card as 64MB or, as lspci reports, 128MB?
...
Is anyone still working on this mod?
Thanks!

Use DIY ViDock Setup's 'compact' utility to compress your 32-bit space and test, noting the lowest position occupied by a device above TOLUD. If system and associated PCI devices work OK then can set TOLUD in the bios to match that lowest position, liberating RAM in 32-bit space.

Hello everybody, I have FS-Amilo Pro V3205 with Intel 945 chipset and similar problem about 4GB RAM.

Has anyone modified bios with new TOLUD register value? It would be nice to test it on my notebook.
Or, I'm going to change motherboard, so please help me which is suitable for to replace intel 945? I've read some about Intel 965 and it seems to support 4GB ram with its ICH-8 bridge, so there is according bios version for it
it is possible get such motherboard from eBay for example with Graphic card, but can I use it in my notebook?

Thanks in advance

little edit: I mean Intel 965 express for notebooks
