Gam, SGAM, Pam, Iam, DCM, and BCM are some special allocation ing tables used in SQL Server to manage space allocation. Understanding their differences and roles plays an important role in understanding the architecture of the SQL Server physical database.
SQL Server zone management (GAM, SGAM)
Global allocation ing table (GAM ):Unified Disk Area. The Gam page records allocated areas. Each gam contains 64,000 zones, which is equivalent to nearly 4
In the previous studies on the BCM version, the WAN port was extended but could not be online due to the lack of in-depth research. Due to the time relationship, the research was not continued.
When I first came back yesterday, I began to study this item and successfully expanded bcm to N Wan. I cut a picture and set one of the four or more ports to online.
In fact, B

Recently there are several small networks that use small bandwidth access, so there are a lot of lines, but there are not many machines that he carries. In this case, the price is a bit high when using the PC version, whether it's hardware, authorization, or electricity! If you do not use the PC version, you can only use hard routing. At this time, BCM is the first choice. I will tell you my research experience on
I believe everyone is familiar with TFTP, right?
BCM-swiping machines: wayos, tomato, ddwrt, openwrt, and so on all need to be used. In earlier versions, you can only open one window, And Then ping 192.168.1.1-t to ping the route's TFTP server, when TTL = 100, click Update route! The TTL process is only about 2 seconds. Sometimes you just skip it when you are not careful. It is really hard to get a route!
However, with this new version and the TFTP
In fact, the memory in the vro consists of three parts: the header is CFE, which is actually the BIOS we are talking about. The following is the NVRAM and firmware area (the two did not study before and after ).
Many of my friends want to use the JTAG line to refresh CFE (for example, if you want to modify some default configurations, or activate memory or overclock). The speed of 8-bit transmission of this parallel port is really slow,
In fact, if the machine has not changed bricks, you can use

The DHD driver layer dhd_xxx.c calls the bus Sdio drive layer bcmsdh_sdio_xxx.c and then calls the Fifo,buf,reg of the controller layer and other TX RX operations. In this series of calls, memory, IO,DMA, interrupts and other operations will use some of the OS interface and structure.Like a generic network driver, the process of the BCM driver, TX data, is to write the Skb_buff data on the hardware header to the TX FIFO or Reg, write to the data Len,
Although it is very easy to extend the WAN port of wayos, sometimes it is too troublesome to modify the script because the WAN port is extended and copied in the whole batch, sometimes I want to change something and try again. It's too tired!
After a while, I suddenly wanted to use the network card. This would be a problem, but don't worry. You can use 1.4 to restore the default function.
It's also software for lazy people, haha
