RTM,OEM, Or a "cracked" version install. What other specs on you machine..are all components able to run vista??..You should ask this question in the general vista forum..
Ga-ma790gp-ds4h Hi Yen, Hi Offon7544! If you are refering to the Mod on the MA790GP-DS4H Bios done by Offon7544, i can report for all to know that this Mod appears to be sort of stable and somewhat safe to flash now. Warning: There was one issue when trying to recover from S3 by using the keyboard (USB) instead of the Power-Switch. When i did this, the OS did not come back online and the Board could not be switched off by power button. It would just hang with fans running and screen black. After a reset the DMI/CMOS data was corrupted. It could partly be fixed by clearing the CMOS, but setting BIOS Options and then saving to CMOS would get the Board into this hang-state again. after clearing CMOS a second time the board would boot again and then report CMOS checksum error, offering to load a clean CMOS config file from BIOS-Memory (emergency-backup config). Having done so, CMOS was overwritten with clean data. The Board would behave normal again. I did then disable wake up from S3 by USB Devices, for this appears to be unsafe. I have not tested this with the un-modded bios, so i cannot verify if this behaviour is due to the mod or maybe a board specific problem ( i have seen this behaviour very often in quite some boards, so it is not necessarily a mod-problem). When vista came back online the first time after this, i had a bluescreen, which occured right after the first keystroke on the (usb) keyboard and which was traceable to a RAM related problem according to some help-sites, partly maybe due to Dual Channel mode. I suspect this being due to the previous BIOS Hickup. It has not happened again yet. Very unlucky for User ttxx, that he bricked is board with the other mods since this would've done the trick at least without breaking the board... Am still very happy about your work, offon7544, really. And Yen, thx again for offering further assistance. [EDIT] All issues as described above turned out to be RAM-related, since i had my RAM running with too low voltage it would just fail and behave faulty. The BIOS from Offon7544 behaves correct, stable and normal!
@911medic - thanks for the reply and sorry if i asked this in the wrong forum. went with your suggestion for now and used the software SLIC emulation which worked great! thanks again 911.
