Moving some initial discussion where it belongs:
Is anyone aware of an ICH6-M-based laptop of any make/model with stock or modded BIOS capable of AHCI? If so I suppose it's something likewise doable on T43...RealBlackStuff wrote:The T43 was the first Thinkpad designed for SATA, hence the (hidden) AHCI in BIOS and chipset.dandreye wrote:Btw what exactly does BIOS do (i.e. send to the chipset etc) when configured for AHCI as opposed to IDE/Legacy/Compatibility? Asking that with my T43 in mind, which sadly has no such switch while ICH6M chipset does support AHCI.
How that works? No idea.
At the time the T43 came out, SATA drives were still very rare and expensive, so it was more user/budget-friendly to add the SATA-to-IDE chip and stay with IDE drives.
The SATA-mod removed that chip and replaced the IDE-connector with a SATA one, the way it was intended.
Everything else stayed the same, except there was now no more drive-capacity limit.
Many thanks in advance!
