Atom D525 detected as 32 bit

Hi all,

Not sure if this is me doing something stupid or just a bug.

I’ve installed Linux Mint on an old Atom D525 based machine. Trying to install the latest nightly in virtualbox and it’s puking, saying that it is designed for a 64 bit machine.

Checking Intel’s Ark site says this processor is 64 bit. Any ideas?

Here’s my host system info:-

Thanks in advance.

Could it be that your machine comes with a 32bit UEFI? If so, you have to set it to legacy mode and boot through the old fashioned BIOS, because we don’t handle 32bit UEFI (but know how to switch a machine to 64bit forem BIOS).

No, no EFI support at all. It’s an old ASUS motherboard. I upgraded the BIOS last night to the 19 Oct 2012 version:-

I’m thinking it could be a weird VirtualBox setting, but can’t for the life of me find it.

It doesn’t have virtualization extensions so will be slow anyway…

Oh, I did not notice that you were trying to run haiku inside virtualbox.
Indeed, without Hyper-V hardware virtualization from the CPU, virtualbox will not only be slow, but also only emulate a 32bit CPU (since it can’t use the real CPU through virtualization anyway).

Aaaaaah that’ll explain it then. I guess I’ll just use this machine as a general server for the house instead.

I have the beefy laptop I bought last year working with Manjaro Linux on it for anything serious. Just trying to build bootstrap for arm on it now following the instructions that were posted on the other thread.

Thanks all.

Two things I can think of are did you select a 64 bit system option, like Other (64-bit) for Haiku? If it’s not a 64-bit option, VirtualBox won’t load a x64 box. Another is I see you’re using an Intel processor with a BIOS; do you have VT-x enabled in there? Without it, VirtualBox will still start and run okay, but not at its full potential. Also, is the board set to the right setting in System (not PIIX3 for example?)

Another option outside VirtualBox if it’s not seeing your x64 CPU at all is to use qemu with kvm, like qemu-system-x86_64 --enable-kvm -m 1G -hda name-of-haiku-hd.img

Hope this helps :slight_smile:

You should read the thread before commenting … the D525 doesn’t have virtualization extensions at all whatsoever. So virtualbox won’t do 64bit… only slow 32bit, the performance of QEMU would probably me limited by this also.
