Public bug reported:
Winbook TW802 - Intel Atom Tablet with UEFI Bios
64bit cpu / 32bit bootloader
Related models: TW700, TW800, TW801 & TW100
Recommend do not install V17.10.1 on those machines until issue resolved
Previous Single boot Ubuntu 16.04.1 installation NO Bios issues:
installed via isorespin from USB
New Single boot Ubuntu 17.10.1 installation caused Corrupted Bios:
installed via isorespin from USB
uname -r = 4.13.0-32-generic
Corruption prevents Bios access to USB, so cannot boot ClonZilla to restore
prior image
Ubuntu 17 boots to desktop but not fully functional: (issues are unrelated to
this bug report)
WinBook Bios
Phoenix SecureCore Bios
Version 1.00 IA32
Build 11/24/2014
Can access BIOS with F2 during boot
But Bios hangs accessing "BOOT" tab that controls boot devices
Will not display & cannot select any boot device
Restoring Bios defaults does not fix issue
Attempted Fix:
Tried 17.10 "SPI" fix - bug #1734147
Neither method shown resolves the issue
after fix applied uname -r = 4.15.0-041500rc6-generic
Fix #1734147 creates other issues:
Bug #1734147 fix prevents access to grub during boot
prior to #1734147 fix,"shift" during boot opened grub menu
after fix, cannot open grub with "shift" or "c"
uninstalled the fix via method shown in #1734147
uname -r = 4.13.0-32-generic after #1734148 uninstalled & reboot
Gathering Info for this bug report
ubuntu-bug linux = gathers the information but;
V17 touchpad issues prevent sending the data
version.log & lspci-vnvn.log are attached.
Once USB is accessed, I can restore prior image
Regards.
