</div>Yep, my laptop has Phoenix BIOS too. Btw, this BIOS has buggy DSDT (thermal<br>
and battery don't work reliably without patching DSDT). But I tested with and<br>
without patched DSDT - so my custom DSDT is not cause of bug in my case.<br></blockquote><div>My laptop (original acer aspire one) uses an H2O Insyde BIOS. I had never heard of Insyde until I bought the computer. Apparently, Insyde's H2O line is EFI firmware.... <br>
