May not have been a popular model or could have been a good initial release that didn't require an update. Good luck!
I got an email back from them, and I was right, there never was a bios update for it. but even then, they used this same mobo in 9 different laptops, why put a hard drive size limit in the bios, then never release an update to remove it in the future? At least I finally got the hard drive to work on it, I ended up partitioning it into 2 primary partitions of 116.4 (like last time), but this time I formatted the second partition as fat32 instead of ntfs, and now it's letting me use all of it without and delayed write errors.
And i'd upgrade, but I only paid $25 for this thing broken (bad hdd, missing keys, dirty, its fixed now), and I cant really afford to get anything better unless I find another broken one for cheap.
