UMBs are unused areas of memory above 640 kilobytes (KB) that can be used to load device drivers and TSRs (terminate-and-stay-resident programs).<\/p>\n<p>To use the <strong>devicehigh<\/strong> command, you must first create an UMB. You can do this by using the <strong>mem<\/strong> command to see how much unused memory you have above 640 KB. If you have at least 64 KB of unused memory, you can create an UMB by typing the following command:<\/p>\n<p><code>memmaker \/c<\/code><\/p>\n<p>This will create a 64 KB UMB. You can then use the <strong>devicehigh<\/strong> command to load device drivers into the UMB. For example, to load the <strong>ANSI.SYS<\/strong> driver into the UMB, you would type the following command:<\/p>\n<p><code>devicehigh=ansi.sys<\/code><\/p>\n<p>You can also use the <strong>devicehigh<\/strong> command to load multiple device drivers into the same UMB. <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n              <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div>       <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> For example, to load the <strong>ANSI.SYS<\/strong> and <strong>GRAPHICS.SYS<\/strong> drivers into the same UMB, you would type the following command:<\/p>\n<p><code>devicehigh=ansi.sys,graphics.sys<\/code><\/p>\n<p>The <strong>devicehigh<\/strong> command is a powerful tool that can be used to free up conventional memory.
