1)Virtual Machines earlier prepared with Linux Mint 16 (64 bits)
do not work Linux Mint 17 (64 (bits),even after downloading latest Virtual Box 22.214.171.124.12-93733-64 bits.While creating new machine with 64 bits OS option for 64 bits is not avalible.I had googled for this,the same problem was reported/discussed in verious forums during 2011.I had installed Linux Mint 17 (64 (bits) on my Toshiba Lapto
The Intel software manual specifies that in IA-32e paging mode the page table entry contains several ignored bits (specifically, bits 11:9 and bits 62:52, for a total of 14 bits). If I understand correctly, these bits can be set to anything. Does any OS or other system use these bits for storing auxiliary information?
Since MS‑DOS, I know system invocation using interrupts. In old papers, I saw reference to int 80h to invoke system functions on Linux. Since a rather long time now, I know int 80h is deprecated in favour of the syscall instruction. But I can't get it working on my 32 bits machine.
Is the syscall instruction to be used on 64 bits platform only?
I have just bought an hp pavilion DV6 ( intel i7 processor + 6G of RAM) running windows 7( 64 bits). I downloaded Ubuntu 12.04 64 bits and correctly burned it to a DVD. My problem starts when I try to boot the computer from DVD as a first step to install Ubuntu. In fact, the home page of Ubuntu is shown without further prompts ( no button of install of try it before install).
My question is if there is a specific way to make coexist chrome 32 and 64 bits version. I have a windows 7 64 bits and I recently install chrome 64 bits to test some java applets, surprisingly the 64 bits version is installed in the 32 bits folder (C:\Program Files (x86)) overriding the 32 bit version.
For some time I've been reading the "Understanding the Linux Kernel" book to learn about memory management in Linux.
In 32 bits Linux, the size of the mem_map array (I know it's not exactly an array, but for the sake of simplicity here I'll say so) can be quite large. For example with only 2Go of RAM, you would end up having an array of 524288 4ko pages.
