Dell 4600 enter bios

[Akerus]

I cannot get in to bios on my Dell 4600 - i am trying to install a new hardrive and cannot get the system to recognize it.

Does 300 vs 150 make a difference?

The Dell Dimension 4600 will accept up to 250 GB hard disk. I checked with Dell tech support, and then installed a 250 GB HDD in my oldest Dell Dimension 4600. Works well. They were clear in telling me that 250 GB is the limit.
