sorry for the late replay, kinda busy last week @Sp0iLedBrAt -In BIOS there are two option IDE MODE and AHCI MODE. I got those problem on AHCI Mode. Installation are work fine in IDE Mode. The built-in OS is Win 7 which many of program from my discipline couldn't install in it. So i hardly to try installing xp, after many times failed in AHCI mode, i finally use IDE mode to install it. And because of that i can't paste in here about Detail Hardware IDs. But before format it, i have read like 'ahci sata 1.0 controller' under Device Manager. I still corious install it in AHCI Mode.... -I had slipstreamed SATA driver for couple times, i learned it from nlite Forum. I used single txt mode driver method. -Yes sir, the type of that portable computer is Netbook. @bsl140990 I got results as same as CPUID, the southbridge is SB750.
