@@ -31,7 +31,8 @@ The hypervisor extension depends on an ``I'' base integer ISA with
 32 {\tt x} registers (RV32I or RV64I), not RV32E, which has only
 16 {\tt x} registers.
 CSR {\tt mtval} must not be read-only zero, and
-{\tt satp}.MODE must not be read-only zero (only Bare).
+standard page-based address translation must be supported, either
+Sv32 for RV32, or a minimum of Sv39 for RV64.
 
 The hypervisor extension is enabled by setting bit 7 in the {\tt misa} CSR,
 which corresponds to the letter H.
