Could you change Serial port1 in the BIOS from 3F8 to 3E8?
Unfortunately, I already moved HOT-433 v4 board off the test bed in order to test HOT-433 v1. The v1 board has a different layout from v4. Version 1 of this board has an older AWARD BIOS option and a newer WINBIOS option.
a) AWARD BIOS - 433AUS23
b) AMI WINBIOS - 433AUS2C
When COM1 is disabled with the AWARD BIOS, it stays disabled in Windows 95 Device Manager. When COM1 is disabled with the WINBIOS, COM1 is NOT disabled in the Device Manager. And in the case of the WinBIOS on the HOT-433 v1 (contrary to the HOT-433 v4), I cannot have the emulator card enabled on COM1 without first disabling COM1 in Windows Device Manager, otherwise, the system hangs on boot (same case with NexGen system).
However, and contrary to the NexGen system, I was allowed to change COM1 in BIOS from 3F8 to 3E8, and Windows Device Manager now shows COM1, COM2, and COM3 - and the emulator card still is working on COM1. Again, this didn't happen on the NexGen board, which for the same conditions, crashed shortly after loading the desktop.
