The hpcmips kernel doesn't do that. The hpcmips loader does that. Once the stuff is loaded into memory, the kernel takes over. Part of that takeover is blowing away the TLB. Once the tlb has been reset, the old WinCE mappings are gone for good. : I mainly want the NetBSD SA-11x0 port to work on our own hardware : where I can just put a different image into flash, so I am not looking : at supporting loading on top of WinCE. OK. The reason that the hpcmips guys went that was was that there's a huge number of WinCE devices, some of which you can get very cheaply, that do not have the option of Flash at all. WinCE is in Mask Programmable Roms. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
