Hi,
i havent looked over the code in alot of detail yet,
buti m guesing the $values['status'] var is the value of either 1 or 0 then,
if so, try changing: <input type="checkbox" checked name="update[<?=$values['id']?>]" value="<?=$values['status']?>">
to: <input type="checkbox" name="update[<?=$values['id']?>]" value="1"<?php if($values['status']) echo ' checked'; ?>>

The problem using chcekbox is when you unchcek it, you haven't that variable in post request variables. So you need to go trough query and check if a row that has status value=1 isn't set in post variables and then update the row. Even so with rows that have status=0. It's better to use select box or radiobuttons. But Ican write the solution for you later.

What you could try is loop the update statement the same as you looped the checkboxes in.
Something like this...
<?php 

if (isset($_POST['update'])) {
	
	$query= "SELECT * FROM product  order by type,-seq DESC" ;
	$result=mysql_query($query);
	while ($row = mysql_fetch_array($result)){
		
		$newval = ( $_POST['update'][$i] ) ? '1' : '0';
		$sql = "UPDATE product SET status='{$newval}' WHERE id='{$row['id']}'";
		if (mysql_query($sql)) {
			echo $p;
			$p3=$p;
			if($p==$p3) $p=' ';
		}
		else echo '<p>Error Updating '.mysql_error().'</p>';
	}
}
