1. Reference http gnats netbsd org 46189 Description Generic splash screen support is performed on x86 platforms via the genfb 4 driver when properly initialized by the bootloader Unfortunately there was a mismatch for the bit order between the driver and the VESA palette in the 15 16 24 and 32 bits depth video modes As a result the colors were wrong for every color except green BGR versus RGB Workaround The patch supplied in the problem report fixes the issue on x86 platforms specifically Additional issues have been observed with ATI AMD Radeon graphics cards but do not affect the WeTab or the IdeaPad S10 3t Resolution In progress Page 38 of 49 DUEKIN consurring WeTab Freedom Report 4 4 4 Intel GMA graphics cards are not fully supported Affected components The NetBSD kernel and xf86 video intel drivers from the base system and pkgsrc Reference None officially Description The graphics card found on both the WeTab and the IdeaPad S10 3t are not supported directly by the xf86 video intel driver and need Kernel Mode Settings KMS support from the system This was not supported by the NetBSD kernel during this project Additional video output connectors may or may not work depending on the BIOS settings when available or the connection to a screen during the bootup sequence A NetBSD developer Gr goire Sutre gsutre 9 is currently working on this issue His progress can be tracked online on h2.
