Undo boot0 change

[fortozs]

Hi. I followed the guide on boot0 error's and mistakenly thought I had this problem running a dual boot. So I ran the following...

dd if=/usr/standalone/i386/boot1h of=/dev/disk0s2 bs=4096

It was after this I realized that my drive was actually a 512k format drive. Surprisingly, it still boots up sometimes, but since then I have been getting a blank screen on many boot attempts. What code would I use to reverse this. I'm tempted to run:

dd if=/usr/standalone/i386/boot1h of=/dev/disk0s2 bs=512

but I figure I'd better ask before I screw anything else up.

bs in the dd command sets the amount of data you send to the device. if the bs is unoptimal it will just slow down the speed at which you write the data.

Thanks. I got brave and just gave it a shot. Seemed to work ok. Think I've finally got my dual boot in full working order.
