This is pretty much a copy of the post I made on the Acer Community forums, also posting here to hopefully get help faster.


I've been trying to install a 2GB RAM stick in my Aspire One D255, however once it's in there it won't boot to BIOS, just a blank screen and fans stop spinning. I've looked around and I think a good step is to update the BIOS to v3.16 (after putting the factory 1GB RAM back in, of course).

I've already wiped Windows off my C drive trying (and failing) to install Kubuntu. So I installed FreeDOS on there and (on another PC) copied the BIOS update files onto a USB drive and then moved them to the root of C on my laptop. The file structure is as follows:

C:\>dir
 Volume in drive C is FREEDOS2016
 Volume Serial Number is 113E-16F7

 Directory of C:\

FDOS                 <DIR> 04-27-2019  3:20p
AUTOEXEC BAT         1,319 04-27-2019  3:21p

PAV70D2  FD      2,097,152 04-22-2011 10:48p
PAV70D3  FD      2,097,152 04-22-2011 10:00p
         8 file(s)      4,816,215 bytes
         1 dir(s)   2,136,309,760 bytes free

Flash.exe, FlashIt.exe & the 2 .fd files are the update files. The rest is part of FreeDOS.

But when I run Flash.exe, I get this error:

C:\>FLASH.EXE
C:\>Flashit PAV70D3.fd /all
DOS/4GW Professional fatal error (1307): not enough memory
one file removed.

mem returns this:

C:\>mem

Before you say "don't bother, just buy a new laptop", I recently received this D255 as a gift.

Please help, as I have 30 days to return the 2GB RAM stick if the problem is with the stick itself (however I highly doubt that, since I bought another 2GB RAM ram stick before this one but that didn't work either).

Booting FreeDOS in Safe Mode made Flash.exe work! My BIOS is now updated to v3.16. Let's hope this makes my PC work with 2GB RAM...
