Linux installed on VMware will emit "toot" alarm sound under Shell due to wrong input command or various reasons, which is not issued by sound card, but alarm of motherboard, so it cannot be solved by turning off slightly. Dormitory often sounded like this voice is very harsh, today found a solution online, write down:

Or add it to/etc/bashrc.

Setting Resolution in Linux Character Interface

vi /boot/grub/menu.lst

| 640x480 800x600 1024x768 1280x1024

256 | 0x301 0x303 0x305 0x307

32k | 0x310 0x313 0x316 0x319

64k | 0x311 0x314 0x317 0x31A

16M | 0x312 0x315 0x318 0x31B

In fact, it is very simple, just grub, edit grub.conf

Add the resolution setting after kernel /boot/vmlinuz-2.6.9-1.667 ro root=LABEL=/ rhgb quiet:

kernel /boot/vmlinuz-2.6.9-1.667 ro root=LABEL=/ vga=791 rhgb quiet

Values for different colors and resolutions

depth-----640x480----800x600----1024x768-----1280x1024

8bit---------769--------771--------773----------775

15bit--------784--------787--------790----------793

16bit--------785--------788--------791----------794

24bit--------786--------789--------792----------795

lilo:

It looks like adding a line vga= 0x31? That's enough (I haven't used lilo for a long time, I can't remember a bit)

0x31? is to set specific resolution values, you can refer to the list, do not set randomly

1280 x 1024 is 0x31 a

1024x768 is 0x317

800 x 600 is 0x314

640 x 480 is 0x311
