What happen to a computer without the rom?

Answer 1

There are many computers that operate without hard disks; some lightweight laptops use flash memory instead of a hard drive; the flash memory is lighter, faster and uses less power than hard drives. There are also diskless workstations that operate using a network; the operating system, applications and data are held on a central server and diskless workstations use the server instead of a hard drive. Depending on what you mean by "computer", items like mobile phones, sat navs and PDAs very rarely have hard drives.

Answer 2

In the classical, common sense of the meaning, no, since you likely meant to ask if it can work without BIOS instructions. Assuming you used ROM to mean ROM BIOS, then no, it won't work without a ROM BIOS. However, true ROM chips have not been used in a long time and it isn't even called BIOS anymore. EFI has replaced the BIOS and NVRAM is used in place of ROM. So you can argue that it can work without a ROM BIOS chip since it might have EFI code on an NVRAM chip instead, but it won't work if that doesn't exist in place of the other.

The BIOS or EFI contains the instructions needed to bring up the computer. Without them, the CPU will try to look for them, not find them, and then lock up, since there would be no instructions to bring up the computer, and the CPU takes things very literally.
