Nova.a

It is a harmless memory resident boot virus. It hooks INT 13h, 1Ch and writes itself into MBR of the hard drive and boot sectors of the 1.2Mb floppy disks. The virus does not change the size of the system memory (the word at the address 0000:0413). On installation the virus decreases that number, waits for DOS loading (by hooking INT 1Ch), and then increases the size of the system memory.
