rabbit1345 Posted June 15, 2013 Share Posted June 15, 2013 Is there a dos version that will work with these cards? Quote Link to comment Share on other sites More sharing options...
svl7 Posted June 15, 2013 Author Share Posted June 15, 2013 Added a version that should work. Anyways, if you have a desktop it's much more comfortable to flash from within Windows. 2 Quote Link to comment Share on other sites More sharing options...
Dopamin3 Posted June 15, 2013 Share Posted June 15, 2013 Added a version that should work. Anyways, if you have a desktop it's much more comfortable to flash from within Windows.If given the option I always prefer to flash BIOSes (especially motherboards) in DOS rather than Windows. It's so easy to do a one time setup on a flash drive to make it bootable. Since DOS is more low level and has less stuff going on in the background, it is much safer anyway to flash In DOS.

shizknight Posted June 26, 2013 Share Posted June 26, 2013 Just FYI to those wondering this is for flashing an ultrabay 750m in a y500 with the latest firmware on the y500 thread. On 5.142 I still get the PCI Block corrupted error. The older 750 firmware flashes but it doesn't seem to remove the 135 limit. The newer firmware throws that error. Edit : Same with the dos version.Edit 2 : Somewhere in all this the older 750 firmware worked and now shows up with the proper (MODIFIED) label in inspector with the limits properly removed. So I think I'm good despite the newer firmware not flashing due to that error. It just means I have different versions between my onboard card and the ultrabay one.

svl7 Posted June 26, 2013 Author Share Posted June 26, 2013 You should be able to force the flash with -4 if you get that error, but just don't use this option for usual flashes. Quote Link to comment Share on other sites More sharing options...
shizknight Posted June 26, 2013 Share Posted June 26, 2013 Still gives that error. Quote Link to comment Share on other sites More sharing options...

iMake Posted July 21, 2013 Share Posted July 21, 2013 Is it worth it to try flashing via DOS if I'm temporarily bricking when flashing on windows? I'm having to connect via the IGP and flash back to stock bios. Quote Link to comment Share on other sites More sharing options...
soakwashrinsespin Posted July 27, 2013 Share Posted July 27, 2013 Is it worth it to try flashing via DOS if I'm temporarily bricking when flashing on windows? I'm having to connect via the IGP and flash back to stock bios.Probably worth a try booting to DOS on a USB key and using nvflash there, although chances are that you'll encounter the same issues with nvflash on DOS and you are on Windows. Personally, I'm never comfortable with flashing on Windows and always use the DOS version. Quote Link to comment Share on other sites More sharing options...
sevensixty760 Posted August 7, 2013 Share Posted August 7, 2013 Do you have a tutorial on nvflash for windows? Quote Link to comment Share on other sites More sharing options...
svl7 Posted August 7, 2013 Author Share Posted August 7, 2013 There's a link in the first post. The usage of nvflash is the same in DOS and Windows. Quote Link to comment Share on other sites More sharing options...
maneil99 Posted August 9, 2013 Share Posted August 9, 2013 How safe is it to flash in windows? I have a ACX SC, if I flash to your ACX bios will my stock clocks be 780 stock clocks or SC stock clocks? Quote Link to comment Share on other sites More sharing options...
svl7 Posted August 9, 2013 Author Share Posted August 9, 2013 If I remember correctly the ACX vbios I posted is SC. With a desktop you can safely flash from Windows. Quote Link to comment Share on other sites More sharing options...
amordeastrum Posted September 7, 2013 Share Posted September 7, 2013 I think this question might be asked before, but if i flash it and something goes wrong, whats the chance of it being a soft break? or a hard break? Quote Link to comment Share on other sites More sharing options...

svl7 Posted November 1, 2013 Author Share Posted November 1, 2013 What kind of system do you have? Quote Link to comment Share on other sites More sharing options...
Khenglish Posted November 1, 2013 Share Posted November 1, 2013 The NVS4200 is directly on the motherboard itself and thus has the vBIOS integrated with the sBIOS. NVFlash cannot read the sBIOS. Depending on the laptop the sBIOS can be difficult to pry open to get to the vBIOS. Quote Link to comment Share on other sites More sharing options...
JadedFTW Posted November 9, 2013 Share Posted November 9, 2013 Is there a version of NVFLASH that works on 64-bit Windows yet? Last time I had to boot from a thumbdrive and having an issue making one bootable at the moment. Quote Link to comment Share on other sites More sharing options...
