Hi Bruce,
I have fucked so much with that file on my system I cant realy
make a patch right now. But in the future I will do that. AnhkSVN supports
.patch. But only only thing this diff does is replaces
while ((uint)page < ceil) {
PageAllocator.ReservePage (page);
page += 4096;
}
WITH
PageAllocator.ReservePageRange(page, (ceil / ADC.Pager.AtomicPageSize),
"Reserve memory below 0x100000 (1MB) for the BIOS/video memory");
Since I changed the PageAllocator to work with Reserverd pages in bulk not in
pages. Then this lowers the ReserveCheck form 256 checks to 1.
Kveðja/Regards

Would you kindly re-send this patch to Pager.cs, as an attachment?
My TortoiseSVN is being cranky about it...
