Hi all, First sorry for my english... I have laptop Alienware m5790. This laptop has Phoenix bios. I want to mount in this laptop SSD hard disk. In the bios there is no AHCI option. On the laptop motherboard are two controllers: a) VIA VT6421A RAID Controller link to the manufacturer's website: via.com.tw/en/products/peripherals/serial-ata_raid/vt6421a/ b) Intel 82801GBM Controller Hub (ICH7M) - this controller in hardware support AHCI mode link to the manufacturer's website: intel.com/content/www/us/en/io/i-o-controller-hub-7-datasheet.html I would like to in this bios: 1) totally disabled in bios VIA VT6421A RAID Controller 2) enabled in bios only Intel 82801GBM Controller Hub (ICH7M) 3) add on this laptop bios Intel AHCI Option ROM BIOS compatible with Intel 82801GBM Controller Hub (ICH7M) 4) disabled in bios combined mode PATA-SATA and have only SATA or where possible enhanced mode 5) add new option in laptop bios: AHCI mode This is link to download bios files for this laptop: sendspace.com/file/ovq0ww Please help me to make changes to the laptop bios. Thank you very much .
Take note that ICH7-M is SATA I speed. Looked now and VIA6421A is same SATA I speed. You will get some performance improving but not so much. In theory SATA I is 150 MB/s in real life you could expect something around 120MB/s or little more in best cases. In AHCI mode IDE port of ICH7-M is disabled,if is used in your configuration then will become unavailable.
gabiz_ro yes, I know the theory and practice SATA I, but SSD hard disk must enabled in the bios AHCI mode. PATA (IDE) port don't need me so it can be totally disabled in bios. Again please someone help me to make changes to the laptop bios. Thanks in advance for help .
