In xen 3.0.4-1 source, where is the *unhook/rehook page table implementation* which is important things in ''writable page table mode''.? I can''t find it. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

At OLS I gave a talk on some of the Xen scalability inhibitors, and one of these was writable page tables. We went over why the feature does not scale, but just as important, we found that the uniprocessor case does not provide any advantage either. These tests were done on x86_64, so I wanted to run the 1-way test on 32 bit to show the same problem. So, I have run with writable PTs and

...up the registers to find out that MEMLINUX is installed? I know it is an int 13h / ah=08h call - but I cannot figure out how to specify the other registers... Also, I need to find a way to be able to: unhook int 13h and int 15h and put them back to the BIOS vectors, and yes, I know some DOSses rehook int 13 - but it can be done.. I need to be able to boot a CD, load the ElTorito driver, put comspec to the CD, and remove the image from memory.... I was going to write a small dos program to do that - but I don't know how to detect that MEMLINUX is present... -Maurice

...that tinybit's modified eltorito.sys appears to work for steve6375's tests, I would wonder if the following GRUB4DOS command-sequence would work: map --mem /fdubcd.iso (0xA0) map (cd) (0xA1) map --hook root (0xA0) map --mem /fdubcd.img (0x00) map (0x00) (0x01) map --rehook map --status root (0x00) chainloader +1 boot
