Yes, XPC7400 will go right on, and work no issues with the 3.3V L2 cache. Just need to change the VCORE voltage and PLL config resistors for desired clock speed.
Unfortunately, so far I have been unable to find a way to change L2 cache voltage on those ZIF CPU boards, so I normally use a 7400 to upgrade those. Last I remember when I messed with this, the L2 cache is connected to the same 3.3V rail as other components/circuits on that board, so segmenting...
12V is only needed to erase and program the AM28F010 EEPROM, which is why it cannot be programmed on-board (the board has no way of supplying 12V needed). In normal operation, the EEPROM runs at 5V.
Yep, you can install that EEPROM no issue, then flash it on-board. That EEPROM runs at 5V, just like the original, so no need to change any resistor position. The only case in which that is necessary is if you switch to a 3.3V EEPROM, which are normally designated with an “LV” in their part number.
A 5V-rated chip is what you want, unless your card has an option to change VCC voltage for EEPROM to 3.3V, in which case you can use an "LV" EEPROM. You don't want an EEPROM that requires 12V for erasing and programming (such as the AM28F010), as it can only be programmed externally in an EEPROM...
1. No need to replace Flash ROM on card in most cases, though some really cheap Chinese ones these days seem to be coming with AM28F010, which needs 12V for erasing and programming, so CANNOT be programmed on-board. This EEPROM will work just fine with my patched SeriTek ROM, but must be removed...
The best thing to do is flash my patched/compressed version of the SeriTek ROM, which can fit onto the original 128K EEPROM that a lot of these Sil3112 cards have. Though this RHC one should have a 512K EEPROM installed already if I'm not mistaken. Regardless, the same compressed ROM can be...
Yep, it will work fine with that chip. Really will work with any chip 64K or larger in size, the only oddity is the “28” series EEPROMs (such as the AM28F010) require 12V for programming, so must be flashed externally with an EEPROM programmer and cannot be flashed on the card. After flashing...
What machine is it? The decompression takes less than 2 seconds to run on even the slowest of machines, so that won't be the issue. Though the SeriTek ROM is known to cause this delay on some machines.
Yeah, you can edit the PCI ROM header of the ROM image to match the values of the Adaptec card. Just requires a bit of hex editing, no checksums need to be updated after modifying that header. The strings in the actual FCode portion of the ROM cannot be modified without other work, though. You...
I guess I should update this thread with info about this upgrade being done on PowerBooks... Short story is, it doesn't work. I tried doing the same 740 swap on a PowerBook 3400C, and while it did chime, it did nothing more than that. No video, and no boot. Re-installing the original 603...
I guess I didn't consider the fact the some clients don't have support for obtaining an IP address automatically. The way I have it set up to work is the remote access server (Shiva LanRover E/Plus) will assign each client an IP address from a range. This is a range between 192.168.2.7 and...
