Hello, I tried to write a piece of code to start vmx. This code is directly interacting with cpu instead of with virtual cpu as in xen. But every time I call vmxon, a GP exception happens. Could anybody help me on this? The following is the context 1. After booting up to the program, I disable A20M. 2. allocate a 4kb-aligned vmxon region and calculate its physical address. 3. setup

Greetings, As a Google Summer of Code student for the SYSLINUX project, I had the chance to learn many interesting things from hpa regarding the internals of SYSLINUX. So besides my main task of implementing ELF modules loading & linking, I decided to put down in the wiki all the information I found concerning SYSLINUX development. In this regard, I have created a special category on the

Hello, I was browsing the code for memdisk (I want to adjust it to my hardware) and noticed a couple of things that I am struggling to understand. I would appreciate if someone could clarify the following mysteries to me: 1) _binary_memdisk_bin_start[], _binary_memdisk_bin_end[] and _binary_memdisk_bin_size[]; These variables are declared (as extern const chat in 'setup.c')

I has a problem of installing windows xp home edition in fedora core 7 with xen 3.1.0. I am using virtual machine manaegr to install winxp home. Things went well until a message pop up as follows "The file ''asms'' on Windows XP Home Editio CD-ROM is needed" A locaton box below this message shows s path

After formatting a floppy to MSDOS format and using syslinux /dev/fd0, I successfully installed ldlinux.sys to the root directory of the floppy. Then I created a syslinux.cfg under the root directtory of this floppy to load the linux kernel in my first hard disk, 3rd partition, boot folder. The file system of this partition is ext3. The floppy has a FAT file system. This config file is listed

Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

...pe: text/plain; charset=UTF-8 Hi, SYSLINUX isn't designed to work that way. It can boot kernel only from same filesystem from which it's loaded. You need GRUB or GRUB4DOS for your task. SYSLINUX can be used to chainload GRUB.

Hello, As it is known, Syslinux loads COM32 modules to 0x101000 (the PM IDT is at 0x100000). Unfortunately, in my project this area of memory is already occupied by another program that I need to preserve for a while (specifically, until Syslinux's COM32 module boots up the OS kernel). In other words, I need to load and execute COM32 modules from other than 0x101000 area of memory (for

Hello, I would like to access Memdisk (as a RAM disk) from my application in pure protected mode. "Pure" means that I don't' want to have any switches to real mode even if these switches are automatically handled by Memdisk interrupt stubs. The reason is that my application is running on top of Virtual Machine Monitor (VMM). This virtualization layer is quite simple and

Hello, I am using Syslinux as a bootloader for a PC-based embedded system. I need to load my ELF applications to the top of the available physical memory. By the way, they have no any relations to klibc or Syslinux since they are compiled with a special embedded C-library. Since different PCs may have a different amount of installed RAM, I may need to load those ELF files to different locations.

A "main" function is defined in Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c. In this main function, rombios, vgabios and vmxassist are copied to specified address, with following commands memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz); ... memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot, sizeof(etherboot)); .... But after searching the whole

Hello, I have noticed that Peter wanted to port newlib to syslinux project some time ago. It seems that the porting was not finished. Peter mentioned (http://syslinux.zytor.com/archives/2004-February/003168.html) that sucj job would require a lot of efforts. At the same time newlib is usually regarded as a "highly portable C-library". I am wondering what are the major
