Hi. I'm trying to add a mode to vidcontrol for a fixed freq. monitor I have. It looks terrible in console mode but I've heard that it's clear in bios mode 0x53. However, when the ioctl call is made with my parameter it fails with errno set to 25: "Inappropriate ioctl for device." My code is almost identical to the existing code in vidcontrol -- all that's changed is the bios mode I am trying to switch to. Does anyone have any experience with this? I'm in over my head and would appreciate the help.
