悬赏贴：如何通过dnsmasq实现bios和uefi双网启菜单

赏金是不少于2年的免费科学上.网或我的800本论坛积分

我的ARM路由器上跑着FreshTomato系统(一种简化版的Linux系统)，其内置的Dnsmasq版本号是2.85，Dnsmasq的配置部分可以任意添加内容。目前我已经可以通过更改路由器的Dnsmasq内容分别实现BIOS网启或UEFI网启，并且用FTP下载大的WinPE文件，现在想自动判断BIOS还是UEFI并实现网启。

要求：
1.自动判断pxe客户端是BIOS还是UEFI，
2.无论是BIOS还是UEFI网启，都能出现菜单，方便我以后添加启动项目
3.通过tftp读取配置文件后，然后通过FTP下载WinPE文件，不用HTTP是因为我的HTTP有其他用途，
4.能提供除WinPE外所有的配置模板文件，不需要我再去不同的地方到处找了。配置模板应该不会很大，如果本论坛不允许上载，可以上载到我的个人FTP服务器。

我目前的配置见附件，很简单，
