...ks to work. I've also seen on their user forum where people have it working, no problem. But when I try to install, I get this: Code: cnelson at pcda5561:~/Desktop$ wine plsqldev715.exe wine: Cannot start DOS application "E:\\home\\cnelson\\Desktop\\plsqldev715.exe" because vm86 mode is not supported on this platform. cnelson at pcda5561:~/Desktop$ It looks like I'm not the only person to have this issue in wine, but I haven't found much (any?) documentation on how to resolve it. Your help is appreciated.

I have my VBIOS reset program working on klibc now. I think I have tracked down and fixed all of the problems I was having. So to make this official I need a few minor klibc additions: 1) fix inb/w/l to return the right variable. 2) implement getpagesize() 3) add support for vm86 - one function and one header file. Later, if you're interested, we could modify the vm86 function to call the x86 emulator lib on non-X86 machines. This would make more x86 video cards usable on these machines. It's 140K library so it would need to be optional. You might want to move the...

Hi guys, At a loss trying to figure why if (has_eflag(X86_EFLAGS_ID)) returns false in my HVM domU. Standard function has_eflag() in cpucheck.c running in real mode. Works fine on PV dom0, but fails when guest is booting on my hybrid dom0. LMK if any ideas. I''ll keep digging in the manuals, but nothing so far. thanks, Mukesh

...un very early since you may want to use one of these cards for your console. Because of this I'm looking at klibc and the early boot environment. The reset program works by getting a copy of the card's VBIOS and calling it's reset function. To do this the user space app needs to go into VM86 mode, or on non-86 architectures run a x86 emulator if need be. You can't call the VBIOS from a device driver becuase it has been written assuming that it will be run in real mode, not protected mode. I tried linking to klibc but I'm missing some key pieces. I need things like inb/w/l(), o...

I haven't followed Wine in quite a while, other than to do an occasional update (but hopefully this will change). I noticed DOSBox support was added in January 2011. My understanding is that when Wine can't even attempt to run DOS programs itself (MAC OSX, 64bit OSes, etc) that it will attempt to run using DOSBox. Is this correct? Is the plan to replace native Wine DOS support across the

All, Given the amount of NULL-pointer dereference vulnerabilities in the FreeBSD kernel that have been discovered of late, I've started looking at a way to generically protect against the code execution possibilities of such bugs. By disallowing userland to map pages at address 0x0 (and a bit beyond), it is possible to make such NULL-pointer deref bugs mere DoS'es instead of code

Instead, to follow hardware behavior, the I/O permission bitmap must always be consulted. Signed-off-by: Jan Beulich <jbeulich@novell.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi all don''t get such envionment to try now. so ask for help here. imagine that two os installed. Xen3.1 + Linux is installed in /dev/hda and windows xp is installed in /dev/hdb I don''t want to reboot to use windows. Is it possiable to boot the hdb windows in xen? i saw there are some threads about P2V in this mail list. will the P2V tools help? thanks

...ppc machines. People do this because the x86 versions are half the price of the OpenFirmware ones. Even x86 machines need to run the ROMs for secondary cards. I'm in the process of modifying fbdev to use hotplug events to run these ROMs. What about including emu86 support in non-x86 builds and vm86 on x86 in klibc? The linux BIOS people have a 40K version of emu86 available. Right now video ROMs would be the only user of this but there are SCSI disk controllers with boot ROM too that no one is developing for. ------------------------------------------------------- On Mon, 07 Feb 2005 09:34:...
