Could this break the 137gb limitation?

[Den Leiw]

When using this hdd enclosure (for example) :

http://cgi.ebay.com/ws/eBayISAPI.dll...110902928&rd=1

Look, it says : Supports 48-bit addressing for large hard drives

you use a usb2ide cable to connect the ps2 to the enclosure

for the power I don't know maybe connect it also to the ps2, but would it get enough energy to make the fan work too, or connect it directly with the AC cord

hmmm I am confused about this...
maybe there are also enclosures that have 48bit support which have an IDE outpout

Has anyone tried sth like that?

Someone would have to come up with some USB 1.1 storage drivers for accessing the hard disk. USB 1.1 is terribly slow, and even if there did exist a driver for using a USB HDD, you would still have to use a boot disc, at the very least, to get games to work.

And they still might not see past the 137gb barrier. I think the limitation is with the PS2 bios itself--but I could be wrong, of course.

The limitation is in the driver that gets loaded. The standard Sony driver only supports 40-bit, but it appears someone has hacked a version, albeit a little unstable to support 48-bit.

if the limitation is in the bios itself ... hmmmm

what about dumping the bios onto your computer (there's a tool for that on ps2dev.org) and then try some hex editing to find the 40 bit restriction

hmm if you managed to correctly hack it (who knows^^) you still have the problem how will you overwrite the bios on the ps2 with your hacked bios ... heh let's try to find a method to create a buffer overflow to do that ^_^ but well if you could do that you could also simply patch your console with another's ps2 more recent bios... Any ideas ?????

Not BIOS, driver that is loaded. It's possible, as someone's already done it, but it's compatibility is sketchy.

I stand corrected--good info too. It made it sound like the biggest problems would come from trying to get normal apps (games) to play nice with applications capable of seeing past 137GB.

Too bad it somewhat seems like the ps2dev'rs were trying to discourage (or at least were not being very positive about...) further development on it because of the probability of it being used for non-homebrew (illegal) purposes.

but it's compatibility is sketchy.

Seeing as most applications are LBA28 and would possibly corrupt some data on the HDD, unless they were patched for LBA48 support
