Lenovo IdeaPad S205
The Lenovo IdeaPad S205 has some issues with the BIOS (Boot loader), WiFi.
The unit used for testing contained the following hardware:
- Processor: AMD E-450 APU (integrated Mobility Radeon HD6320)
- WiFi: Ralink RT3090
The IdeaPad uses a BIOS based on the SecureCore Tiano Platform. It supports UEFI and Legacy booting, but you can't manually switch between them. From what I found out it depends wether the disk is partitioned as GPT or MBR. However it doesn't have secure boot.
The BIOS firmware has got a lot of bugs. If anything related to it doesn't work, try loading setup defaults.
Follow the Installation guide until bootloader installation.
You can not use the GUID Partition Table and still boot using legacy BIOS. If your desired partition layout doesn't work for MBR you must use UEFI.
While installing the bootloader, you might get the error
Failed to create EFI Boot variable entry: No space left on device
The firmware wants the
.efi-file to be the UEFI default loader, specifically
The firmware does not seem to be able to boot any other file, thus giving you the above error message.
The trick is to just copy your bootloader, (
systemd-bootx64.efi, etc) to
<ESP>/EFI/boot/bootx64.efi and reboot into your system.
Drivers work out of the box.
If you're using UEFI, your device might show up as hard blocked. This is due to a bug in the BIOS firmware. You can fix it by doing the following things:
- Go into BIOS settings and reload factory defaults
- If WiFi still doesn't work change the boot order so that it boots from PXE (PCI LAN) before booting from Hard Drive.
Works by installing thepackage.
Detected by ALSA automatically.
The open sourcedriver works fine and is recommended.
You can also install the proprietary Catalyst driver, but it causes glitches when waking up from hibernation. Also you may run into errors when using the HDMI output on some Monitors.
