Stuck on “reading file 901.ROM” – why EeePC 901 BIOS EZ-Flash isn’t working for you, and how to fix it

I had some fun last night flashing my EeePC 901’s BIOS up to the latest version.    I got the firmware from here and followed this guide.

My Eee sat there displaying “reading file 901.ROM” for about five minutes until I gave up and turned it off.

After a bit of Googling and a bit of thinking, I found the answer: the 4GB pen drive I was using was too big.  I’d formatted it in FAT 16 as required, and allocated a tiny 20MB partition so it wasn’t over the size limit.  Even so, EZ-Flash wasn’t able to read from it.  The limit seems to be 2GB, but I haven’t tested this – luckily I had an old 64MB pen drive lying around from 2003!  Even better, it was already formatted in FAT 16! 😀

I’m documenting this here to help anyone who has this problem in the future.  Good luck!

    FWIW, I’ve been struggling with this on my 1000H for weeks now. Same problem, stuck at reading file 1000H.ROM. I found an old 128 MB stick, but that doesn’t help either.

    Okay, so I worked it out. The solution was to follow “Drew”‘s instructions in the comments of the linked page (i.e. align to cylinder, etc.).
