Hello, I have a Dell Dimension 4600 which originally came with XP Pro SP1. I wanted to have a dualboot on this machine, so it would be able to run DOS games that don't run correctly under XP. Here are the specs: 2.8GHz Pentium 4 Northwood HT 2X1GB RAM Nvidia GeForce FX 5500 250GB SATA HDD (I have an old Maxtor 40GB that's IDE, but it won't be sufficient for my needs). Creative Labs Sound Blaster Live! 5.1 NOTE: The specs I posted are NOT original to the system (enter 6Z5MW0J as the service tag to see the original specs). I have done some research already and found that you need to run setup with the "/p i" switch to prevent ACPI problems after you install the video card driver. I am installing Windows the "OEM way". This means I make the HDD bootable using the /s argument, go into the C: drive, make a folder path called Windows\Options\Cabs. Then I copy the 98SE files that are in the "WIN98" folder on the CD to the cabs folder. The problems I am experiencing is, firstly, when setup loads, it has this weird issue where it delays and won't do anything until I press a key on the keyboard or move the mouse. What it is doing is what I did before (IE, I press the down arrow on the keyboard, and the computer won't show/do it until I move the mouse). This carries on until the first half of setup is completed and the computer reboots. The second issue I am having (and this is where the computer will lock up) is during the second half of setup (where I enter the product key, Windows will scan for plug-n-play devices, etc). Setup will configure the programs on the start menu, and that's it. The whole system will lock up, and there is no disk activity. I have tried a number of options in the BIOS, such as disabling Hyperthreading. Any ideas? I have it set to "OS Install Mode" which limits the system to 256MB RAM.
