DOS 6.22 and earlier can only recognize 2GB partitions. If you have 4GB it must be divided up into multiple partitions, e.g. C drive and D drive. The BIOS limitation is different, this is a limitation of the FAT file system used by DOS.
(Note: It is possible for larger partitions to be used if you have certain software that load PRIOR to DOS loading, i.e. a dynamic disk overlay)


: DOS can see drives that are bigger than 2 gigs. I have a 4 gig and boot straight to my game launcher in DOS. It sees the whole drive. Now on older computers the BIOS could only see 2 gigs of a drive.


: : If you are planning on having 6 to 8 GB you should not install DOS unless you want multiple drive letters (DOS only supports 2GB per drive).

: : To get the same effect as pure DOS in Win95 or 98 you just change one line in the file 'msdos.sys'. It is a hidden file in the root of your C drive.
: : Change the line that reads BootGUI=1 to BootGUI=0
: : Now your PC will boot up to a C: prompt allowing you to run ArcadeOS or whatever.
: : To enter windows type 'win' on the prompt and press enter. To have ArcadeOS start automatically when your PC boots add the command to the last line in your 'Autoexec.bat' file (remember to include the full directory name). So if your ArcadeOS was in the directory 'Arcade' you would add 'C:\Arcade\Arcadeos' to the last line.
: : (Ignore all the quotes above, they are only here for readability). Hope this helps.

: : : Okay, I'm getting there. I think my hardware configurations are just about figured out. Now, I'm going to get a pc and dos right from it. However I'm going to have windows installed to make changes to it. I'm 19, so I've never had to deal with dos and therefore no nothing about it. How do I make my computer boot directly up into dos when I turn it on? How about booting directly into arcadeos on turn on (I believe that this is what most are doing)? How do I type command lines in? i.e. I see something that says type ARCADEOS at the command line prompt so I type exactly that and it says invalid command blah blah blah. What I want to do is get a pc, install windows, and put all the emulators that arcadeos supports onto it including all of the roms. I figure this will be about 6-8 gigs. I want it configured so that when I turn my pc on it does the little beep thing and boots straight into dos but will allow me to exit out and into windows if I need to. One last important question. I don't want to destroy my arcade monitor so if I fire up arcadeOS and everything is great and I exit out of it and into dos, won't the new vga frequency kick in and hurt my monitor? Thanks a ton everyone. I'm going to write an extensive web page on all of this with pictures to "give back" what everyone has helped me with. You guys are awesome. Thank you.

: : : p.s. Does 35mm film scan good? I don't have a dig. camera. Also, what type of wire to buy for my project?
