The front page of Bombay Stock Exchange website takes some time to load due to various Java features. There are many sections and subsections. If you want to download historical data for shares and indices, you really have to be patient in locating the right links. I have given two direct links for historical data.
For historical data of stock prices, this is the link. You can search by Company name, Scrip Id, or Scrip code.
For historical data of indices, this is the link.
