4d5d31170c BIOS: Fixed lslul helper function similar to lsrul. 2024-05-09 09:41:06 +02:00
Volker Ruppert
49736ddcf0 More accurate fix for the BIOS issue #268. 
- lcmpul needs to preserve EAX and EBX, since the result is read from status flags.
- lsrul should not preserve EBX but ECX. The loword of the argument and result is in AX
  and the hiword in BX. Now doing the shift operation with the 16-bit registers
  (lsr bx / rcr ax).
- TODO: the other helper functions need to be reviewed.
