Viglen Ethergen PnP 2000A
The Viglen Ethergen PnP 2000A is a 10Mbps ISA network card. It can be configured in either Plug-n-Play mode (which requires a PnP BIOS or configuration manager) or jumperless mode, where the base address, IRQ and other settings are changed via the manufacturer's configuration utility and no PnP manager is required.
This card's boot ROM socket will take a standard 28-pin ROM chip. It has also been successfully tested with a 32-pin ROM chip using an adapter. XTIDE will run without any problem.
The card's DOS drivers come with a configuration program (DIAG/SETUP.EXE) that can be used to enable the ROM socket (it is disabled by default) and set the base address, as well as adjust all the usual options like I/O address and IRQ.
If shadow RAM is active, the configuration utility will report all shadowed blocks of memory as in-use, and will force you to choose a different address. This means every time the utility loads while shadow RAM is enabled, it will force the boot ROM's address to be moved. Once the address has been set however, shadow RAM can be re-enabled without any problem.
- I/O address: 220, 240, 260 ... 3C0, 3E0.
- IRQ: 2/9, 3, 4, 5, 10, 11, 12, 15.
- Boot ROM: C000, C400, C800 ... D800, DC00, Disabled.
IRQs 10+ are only available in 16-bit slots, however even when the card is in a 16-bit slot it often seems to be stuck in 8-bit mode according to the diagnostics, meaning IRQs 10+ are never allowed to be chosen (tested in a Headland HT12 286 motherboard.)
