New Agian

[Boot_WB]

Hello, welcome to Amiga.org.

If there was a rank of first postings on A.org, that would probably come very high :-) .  The installation of the OS doesn't copy the installer program from the floppy to your hard drive during installation.

Assuming you're using os3.0/os3.1 You need to copy 'installer' from your 'install' disk to the c drawer on your system partition.

Again: welcome to Amiga.org

If you're just using the supplied file system with OS3.x you will want to split the hard drive into partitions of no more than 4GB.  However, you're probably better off with a 150MB - 500MB Workbench partition (make this bootable, install the OS into here), a Work: partition of 1-4GB (install all of your programs here) and whatever you want to do with the rest of the space.  I have a 2GB partition called My_documents: (guess what goes here) and another called Storage: for keeping all my downloaded zip files, backups etc.

For notworking the PC-Amiga you may want to try samba (available at aminet (http://www.aminet.net)) along with a tcp/ip stack such as genesis or miami.

There's a good guide for configuring these at http://samba.amigaworld.net/ .

Out of interest, which version of the operating system ar you running?

Ahh, from your post (ie the mention of the 10GB hard drive) I thought you had installed to a hard drive.  You can, of course, use the a1200 without - but linking it to a pc?  That may require more space than just your ram supplies.

Out of interest - what are you trying to link it to the PC for?  filesharing?  internet?  Just for fun?  
How are you physically linking it?  Are you using a serial cable?

The installer program for the most part is just used for installing to the hard drive, so.......

Ahh, have just googled Ami-PC.
Serial cable connection, mounts the PC drives for use on the amiga.  
I assume there are installation/operating instructions with it?  

The website suggests you can just run it from the floppy though, you shouldn't need to run anything which requires the 'installer' program.

Assuming you towerise it, to use the Voodoo (versions 3-5) cards you would need a Mediator busboard.  
(Cue Amigakit with a helpful link where to buy them :-) )

There are several types of card you can use (see http://www.elbox.com/mediator_driver_guide.html for a full list) although the 3dfx Voodoo ones are the best.  NB - these are the PCI version only, not the AGP - there is no AGP slot on any amiga 1200 busboard at the moment.

However, the tower alone will cost you £50 at least, the mediator another £75-150 on top of that, and you're going to want an acclerator with that (another £50-200) - depending what you are using your amiga for of course.

For now - assuming AMI-PC doesn't fill your expectations - you're best off sticking a hard drive in the amiga, and seeing where your needs/appetites take you naturally.  
You already have a ram expansion, that's plenty for the old games you are playing through UAE.
