Proof step 1 from proof disk-layout-not1-unfold (conclusion)

⊦ m2 ≠ 1 → ( disk-layout(mksb(adr0, m1, m2, m3, m4, m5, m6), # lpt) ↔ m2 = SB_LOG + 1 ∧ m3 = SB_ORPH + 1 ∧ m5 = SB_LPT + lptlebs(# lpt, LEB_SIZE) ∧ m6 = SB_LPT + 2 * lptlebs(# lpt, LEB_SIZE))

System applied rule normalize

And obtained the following new goals

Proof step 2:
⊦ disk-layout(mksb(adr0, m1, m2, m3, m4, m5, m6), # lpt) ↔ m2 = SB_LOG + 1 ∧ m3 = SB_ORPH + 1 ∧ m5 = SB_LPT + lptlebs(# lpt, LEB_SIZE) ∧ m6 = SB_LPT + 2 * lptlebs(# lpt, LEB_SIZE), m2 = 1
