Just upgraded to a new ssd and would like it to run properly. Sata options in bios are either raid or native. Specs for chipsets indicate the board should support ahci it but it seems lenovo locked it out somehow
as read from cpuZ:
Lenovo H405 desktop
Motherboard LENOVO Tilapia CRB (M3A760M v:1.01 printed on board)
Northbridge AMD 780G
Southbridge AMD SB700
BIOS LENOVO
Version D2KT31AUS
as displayed on boot:
American Megatrends Aptio 4.6.3
version 1.24.115
printed on bios chip:
686
AMIBIOS
C 1999
YY53
5136
I dumped the bios using AFUWINGUI.EXE aptio v3.04.02
I opened the rom in amibcp and yes is selected under show for every option but most do not when you load into the bios, and every Access/use is set to default. When navigating to devices\ata drive setup\onchip sata type the only options are native or raid. If I open the strings tab it does have all the ahci strings as though the options exist but are hidden. I was going to change the access/use and then flash the modded rom but tried a flash of the clean rom I dumped before hand and I simply receive "error 7, bios checksum error" and no flash occurs.
Thanks in advance
