In Reply to: BIOS Update for a Sony Vaio PGC-505FX... posted by dave on February 18, 2002 at 11:15:03:

: I need a bios update for a sony vaio pgc-505fx that will allow me to see a harddrive that is larger than 8 GB. I have a 20 GB harddrive, but the current Bios (Pheonix 4.0 Version 6) only allows me to use 8.0 GB of it. HELP!!! Thanks


I see some choices, there may be other good ones:
1. Get a 6+ GB HDD and forget the 20 GB drive. I have not found any 8.4 GB internal laptop HDDs (6, 6.4, 10, 20 - yes, external - yes; but NOTHING internal between 6.4 and 10 GB); 8.4 would be great if you find it - let me know if you do - I'd like a good one.
2. Get an IBM 10 GB HDD and trim it to 8.0 GB with IBM's "Feature Tool" (this is REVERSIBLE according to IBM).
3. Get a BIOS update from the laptop maker (Sony in your case). Search the maker's web site and if you can't find what you need, PHONE their Tech Support to see if they can help (e-mail is often ignored).
4. Consider a custom BIOS (expensive) from Unicore at:
http://www.unicore.com

As a LAST RESORT you can get a drive overlay program such as Disk Manager or EZ-BIOS or ... that provides a software BIOS patch to support larger HDDs. This SHOULD work "OK" on a laptop with a single HDD until the laptop fails and you need to recover the files from your laptop HDD by using a desktop PC. The usual problem is that you can see one or the other of the drives but NOT both at the same time because different address schemes are used (well, you COULD get lucky, but I only hear about the ones that fail!). You can MINIMIZE the impact of a dead HDD or laptop if you establish a good backup procedure (copy files you need to keep to CD-R) and FOLLOW IT.

Hope this helps,
Henry
